Quartz Definition and 36 Threads

I never had quartz clock I see you need to use carbon battery, I am thinking start with 1000 ohm resistor and see if clock runs with alkaline battery if not just keep lowering resistance.

I just encountered an RF cavity in the wild for the first time. It was used as the frequency reference in the Agilent 8640B RF signal generator, which I believe dates back to the 70's. Were quartz oscillators not an option back then? Or were they worse in stability back then? I'm curious about...

I am curious if it would be possible to put a quartz crystal at the bottom of strong cylinder vial with half the crystal hanging out the bottom (but sealed) and have mercury on top of it and then pressurized if it would create a constant vortex? If the mechanical force of the pressure from the...

Why quartz has a higher melting Temperature than glass? Which one is harder and why?

Hi, I've been looking at the optics of ##\alpha##-quartz which comes in two parities, left and right. Quartz is optically active which means that the plane of a linearly polarized beam propagating along the optic axis is rotated by an angle proportional to the distance traveled. I would like...

we have heard that pyramids, old temples are made from hard stones containing quartz crystals. Is they radiate any kind of energy so that we get a pleasant feeling?

Is it made of quartz or stainless steel/aluminum or what? Does it matter which?that's all I need to know, I just can't seem to find if they can be made of standard vacuum metals or if they have to be quartz. Only really seen some diagrams mention quartz tubes but the pictures of large ones seem...

I am trying to get a glass substrate, which is transparent. However, I need this substrate to have low fluorescence. I know fused silica, quartz and Borofloat 33 are transparent but I don't know which one has the lowest fluorescence. I checked google but can't find any data that directly...

I am looking over the supplies on University Wafer until I notice the following: link: https://order.universitywafer.com/default.aspx?cat=Borofloat%2033%20Glass&diam=100mm They sell quartz, fused silica and Borofloat glass as different products. I thought quartz and fused silica are the same...

Hi Where can I buy Piezoelectric sheets? Similar to the one shown in the picture. Thanks

Hi All! A little background info. I'm working with cardiac pacemaking devices with the overall scope of implementing piezoelectric energy harvesters into the devices. I'm in the initial stages of research and development. Okay, so this is my conundrum: I have an output pulse circuit as shown...

Hello, I am doing a project which involves very hot confined plasma. The problem is, quartz tubing is way too expensive for me. I don't want to deal with impurities so I came to ask if you can suggest any cheaper alternatives. Here are my ideas: Borosilicate glass with "getter" coating. (I...

Homework Statement Piece of quartz containing gold weights 102,5g and average density is 7,98g/cm3. Density of quartz is 2,65g/cm3. How much does gold weight? Homework Equations ρ=m/V avg.ρ= m1+m2/V1+V2 The Attempt at a Solution Using average density I find that volume of this piece is...

Homework Statement In a quartz longitudinal waves produce peaks on the 2 sides of the plate. the base frequency is: ##f_1=\frac{2.87E5}{s}## Where s is the thickness. calculate Young's modulus of quartz. \rho=specific mass=2.66[gr/cm3] Homework Equations \lambda=wavelength, u=velocity...

Hi guys, I am a new user of QCM and I am having trouble reaching equilibrium. I have isolated the chamber from air flows and vibrations, the crystals are clean and all the other removable parts have been cleaned as well. The real problem is that sometimes I have managed to reach equilibrium...

Hello :) I am Jon and I am conducting an experiment with Quartz Crystals to test their piezoelectric properties. I wanted to ask you a question about my experiment set up. Which type of force is required to be applied for voltage to be produced? Could I apply a compressive force with...

Hi everyone. I have been reading on capacitors and dielectrics , before that i was reading up on piezoelectric materials like quartz crystal. My question is , what would happen if we put a layer of quartz crystal between two parallel plates of a capacitor ? I think quartz is a dielectric...

I have a problem about the vibrational modes of a quarts crystal Two vibrational modes are induced simultaneously in a quartz crystal at MHz frequencies via a transducer hooked up to two signal generators it appears as if a third average frequency is also generated but only becomes...

Hi all, I have been looking at quartz and trying to work out the physics at a atomic level, how it reacts with photons/laser is of particular interest. I will leave this open as any knowledge you have is welcome, there is the obvious it converts electrical to mechanical and vice versa but...

Quartz crystals are used in clocks to regulate time measurement. Does a quartz crystal convert heat energy to AC electrical energy? Duordi

Algebra - "Quartz Tuning Fork" Watch Homework Statement Many modern watches operate based on a small quartz tuning fork which transduces a mechanical oscillation into an electrical signal. The frequency of the tuning fork is inversely proportional to sqrt(l), with l being the length of the...

if you roll a quartz ball into another quartz ball... If you roll a quartz ball into a stationary quartz ball what would happen to any electrical energy in the collision? My guess is that the structures would need to be in perfect alignment for any meaningful electrical energy transfer and any...

I hear someone said Quartz can naturally vibrate without applying voltage for healing application. Will it be true? Is there any device to measure this vibration? Furthermore, he describes that Quartz can be a device for data storage, which is proved. Will it be true? I know Quartz vibrate with...

So how many pounds does it take for quartz to break into several diffrent peices?

Hi, I am wondering if anyone can help me with a strange request... I am looking to find out if there is any way with the help of an expert I can recreate the same or a similar effect of the rainbow/iridescent effect that is found on titanium rainbow quartz crystals? This could either be on...

Homework Statement The drawing shows a crystalline quartz slab with a rectangular cross-section. A ray of light strikes the slab at an incident angle of 1=34o, enters the quartz and travels to point Po (Figure2). This slab is surrounded by a fluid with a refractive index n...

I want to know the basic principle of working for quartz crystal microbalance, how it is used to measure the thickness of the film?And why it can work at room temp (with water cooling) and at higher temp say 65deg ??

when reading about the main differences between crystal resonators, oscillators and filters there's not much difference in operation, except that filters seem to have the crystal resonators and capacitors and resistors, And resonators seem to oscillate when the proper frequency is applied, And...

When it comes to the piezoelectric effect you can have a small quartz crystal and apply a force to it and get thousands of volts as a result. But if you took a quartz crystal and applied a thousand volts to it, would it just crack? For a quartz crystal to take a couple thousand volts charge (no...

I'm wondering can electrons travel through quartz at any great distance. I'm assuming since quartz is an insulator they will not be able travel any apreciable distance within the material. Say if we got some extremely high energy electrons and fired them at a quartz slide, would any of...

Is it true that, if power were applied to a one meter cube of quartz crystal and the crystal were driven to the breaking point, the gravity waves produced would definetly, 100%, be orders of magnitude too weak to be detected? Apparently Albert Einstein calculated that
