Specifications

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

Clear round quartz plates quartz disc:

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:How many oxygen atoms are in 3.80 g of quartz?: Galena is lead ore. Quartz is mostly made out of silicon. Look up the atomic numbers on the periodic chart and then you can tell me.

Q:What's the difference between an 'Automatic' and a 'Quartz' watch?: I okorder

Q:Will quartz break with a distinctive cleavage when struck?: gold sometimes is found in hydrothermal veins composed of different gangue minerals - adularia, albite or barytes. It relates to the complex composition of the original hydrothermal fluids. Under intense pressure, the correct Eh and pH, these superheated fluids can keep some peculiarly complex chemicals in solution but as soon as one of the factors above (pressure, temperature, Eh or pH) changes, the minerals precipitate out of the hydrothermal fluids. Gold has an affinity for arsenic and also for iron - hence its association with arsenopyrite and pyrite. In arsenopyrite, tiny gold particles reside in cleavage cracks whilst with pyrite tiny particles occur within the crystals as a result of ex-solution from where gold could be tolerated within the pyrite crystal structure when at higher temperatures. As for quartz and calcite, silicon dioxide is frequently in excess especially if the host rocks are felsic. As regards calcite, dissolved carbon dioxide in a hydrothermal system helps it move upwards into accomodating spaces. This carbon dioxide then reacts with calcium ions from either the stoped out host rock or from ions naturally occurring in the hydrothermal fluids.

Q:Thanks!: Hydrochloric acid dissolves only the calcite. Calcite has a hardness of 3, and quartz 7, so you could see which scratched the other, the quartz will not be scratched by the other. The same volume of quartz is not as heavy as the same volume of calcite. Specific gravities are 2.6 to 2.65, and 2.71 respectively, so that might be a close one if you have small samples or imprecise equipment.

Q:I am not sure if this is quartz. I don't know much about quartz but this rock I have is brittle and believed to be quartz and was found with many others that looks similar. I have been looking for a rock that I can start a fire with. If this is a quartz rock then what type of quartz is it?: It can only be dangerous if you throw it at someone. I have a piece of petrified wood from the Windgate formation in southern Utah. It is mostly brown with black streaks. The black is uraninite, (aka uranium oxide) but even the radioactive mineral does not give off enough radiation to be dangerous. Dont over think it, your smoky quartz probably was irradiated (either naturally or artificially) but neither the silica, oxygen nor trace metals are radioactive.

Q:Are they pure quartz or actually just glass? I'm talking of those clear vases and fancy shot-glasses etc. which people refer to as being made of 'crystal'.: Quartz okorder

Q:Which mineral weathers faster-hornblende or quartz? Why?: Amethyst is a good stone to rub on your forehead to try to ease headaches, and when worn as a necklace is good for meditation and that. It is also used as a dream stone for good dreams and is good for helping treat insomnia. It protects against witchcraft. And is also good for healing. Clear quartz is good for enhancing the powers of other crystals and stones. It works well with amethyst.It is also said to have cooling powers and is a good stone for romance. It is also good for meditation. Obsidian is a stone which is good for protection. Very good for protection. Blocks negative energy. And it used to be used for making weapons like spear heads and arrow heads. There are many types of Obsidian like Snowflake, Rainbow, Gold Sheen and Mahogany.

Q:My teacher said we have a lot of quartz in the Philippines, but we do not have quartz sandstone. Is this true? If it is, why? If you can, please answers this question as soon as you can... I need it tomorrow. tnx! T_T: First off, why were you sniffing Quartz powder? You can't have any kind of chemistry training or you would know that you aren't supposed to smell something directly, you are supposed to WAFT the air above the substance to see if there is an odor. And I really doubt that you are going to have any adverse health effects from this, unless you snorted it like cocaine.....

Q:1. As small clay minerals that are deposited in lakes and the sea2. Quartz does not weather and so it keeps the granite from weathering3. It ends up as sand in rivers, dunes, and beaches4. It is converted into feldspar and weathers into clays: Kelloggs96 is correct. You could simply look at the wiki article. A quartz clock mechanism is put to a potential and vibrates at a frequency. There are very fast quartz clocks (greater than 4MHz) and very slow ones that work in watches.

We are one of the earliest companies to develop the production of quartz glass products in China. We have the best comprehensive processing ability, and a variety of testing technologies. We have strong technology and many talents engaged in the processing of quartz glass and advanced production equipment. The melting point of our products is up to 1730 degrees.
