Specifications

Square transparet quartz plate have the features of high purity,heat resistance and low coefficient of thermal expansion.

Square Transparent And Translucent Quartz Glass Plates:

Quartz plates, SiO2≥99.99%. The quartz plates have the features of high purity,heat resistance and low coefficient of thermal expansion. It is transparent with good transmittance of visible light(>90%).

Specifications: length 10-1200mm, Width 10-800mm, thickness1-40mm.

The quartz plates are widely used in the fields including semiconductor, light sources, communication devices, laser instruments, optic instruments, lab instruments, electricity devices, metallurgy, medical and chemical instruments, building material, defense industry and so on.

Q: I've bought a smoky quartz about 25 years ago. A friend told me it could have been irradiated to get its dark colour and could still be a little bit dangerous for health. Is it possible ? I bought it in Canada, don't know its exact origin.Thank you.: Automatic one's are more classic and durable compared to quartz ( of course it is accurate)

Q: how to extract gold from quartz, when it does not appear naturally in metallic form?: The quartz crystals are all over new england and the world usually you can stop them in an outcropping of granite white crystals are common no need to look to far

Q: how much is little chunks of it worth: Quartz okorder

Q: I am struggling with this question the answers of the books are different. Can someone help me with this?: The mass of quartz is of no interest. The important question is: how much gold is present? The chemical reaction is: 4 Au + 8 NaCN + O2 + 2 H2O → 4 Na[Au(CN)2] + 4 NaOH (1 g Au) / (196.9665694 g Au/mol) x (8 mol NaCN / 4 mol Au) x (49.00727 g NaCN/mol) = 0.5 g NaCN So for each gram of gold you need 0.5 gram of sodium cyanide. (If you use potassium cyanide instead, the amount needed is closer to 0.7 gram.) In order to find the amount of cyanide for each kg of quartz you need to know how much gold is contained in each kg of quartz. That is, you need to have your quartz assayed. Most importantly: If you must ask this question on YA, you don't have enough experience to be fooling around with cyanide. You are likely to kill yourself. Leave the cyanide alone.

Q: I think it is quartz?Would it be worth anything like this? would it be worth anything if it was cut polished?Here are some pics:(that's my photostream with the pics in it!): Your question is a false dichotomy... quartzite (metamorphic rock) is composed of quartz (mineral). Quartzite is formed when a quartz arenite (sandstone) is metamorphosed under high temperature and pressures. The original quartz grains recrystallize, creating an interlocking mosaic . This explains why, at the microscopic level, you are having difficulty distinguishing the two. They are identical!

Q: WHy is quartzite harderand more resistant than it's parent rock (which is quartz and sandstone)???: Let qi = angle of incidence and qr = angle of refraction. Then Snell's Law is ni sin(qi) = nr sin(qr) If the light is coming from the air into the quartz then ni = 1 sin(qi) = nr sin(qr) ---> nr = sin(qi)/sin(qr) Plug and chug.

Q: I have read that when quartz is heated to a certain temp. it begins to emit electrical pulses. It is utilized in various devices like watches and crystal radios. How is this done and are there more effective or powerful natural crystals or minerals? Where can a layman find comprehensive and easy to understand how-to info. online?: It ain't quartz

Q: Does copper react with quartz crystal?: No, they are not real diamonds. Herkeimer diamonds is a lay person's / rock collector's name for a double-terminated quartz crystals found Herkimer County, New York and surrounding areas. They are found in cavities that occur in dolostone layers that are part of the Cambrian-age, Little Falls Dolostone. Although they are not diamonds, the exceptional clarity of Herkeimer diamonds and rarity of doubly terminated quartz crystals make Herkeimer diamonds very popular among rockhounds and rock and mineral collectors. As a result, they are far from worthless. For example, current (2010) prices for an individual Herkeimer diamond can range from 10 to over a 100 dollars depending on size, clarity, and the presence or absence of flaws. Clusters of Herkeimer diamonds can sell for over 200 - 250 dollars.

Q: i need to know how much it is worth for my little brother. please elp me. he needs this by Feb. 1. which is tomarrow.: Quartz has a hexagonal prism shape and it has a hardness of about 7. No cleavage, just conchoidal fracture. Muscovite mica is light coloured and breaks off into think sheets because of its basal cleavage. Biotite mica is similar but it tends to be dark brown or black.

Q: What's your favorite crystal? :-): Pure quartz is silicon dioxide: SIO2. It's the most common mineral in the earth's crust.
