Physical Characteristics
(1) with a brittle
(2) has a pyroelectric
(3) the refractive index of 1.533 ~ 1.541, 0.009 difference in birefringence dispersion 0.013
(4) has a strong piezoelectric quartz (Piezoelectric property), that is, will produce sparks when struck friction force, which is the method of flint to make fire.
(5) Common quartz inclusions are: the crystal (Hair crystal) - mainly rutile; grass into the crystal - mainly tourmaline; water bile crystal - liquid inclusions in quartz; green quartz - containing blue rutile needles; milk quartz - causes cloudy water from the fine pores; green quartz - by plate-shaped chlorite or debris may sometimes be green needles of actinolite; Aventurine (Aventurine) - quartzite green or reddish-brown interior contains fine mica sheets, also known as Yao quartz, commonly known as Aventurine. Frequently Smoke black to dark brown smoky quartz, mainly because these rocks contain large amounts of radioactivity have relations uranium, thorium elements.
Material property characteristics
1, scraping not spend
Quartz content of up to 94% of its quartz, quartz is the nature of natural mineral hardness only to diamond, high surface hardness of Ta Mok's hardness 7.5, much larger than the kitchen knife used shovels and other weapon, is not it scratch injuries.
2, do not pollute
Quartz is manufactured under vacuum Biaoliruyi, dense non-porous composite material quartz surface pH of the kitchen has an excellent corrosion resistance, daily use liquid substances do not penetrate the interior, long placed simply liquid surface clean and bright with water or other cleaning agents can be erased with a cloth that can be used to scrape the surface of the blade retentate when necessary.
3, with no old
Dan Guangze bright quartz surface is the result of more than 30 channels of complex polishing treatment process will not be scratching knife blade will not penetrate a liquid substance, no yellowing and discoloration and other problems, routine cleaning simply rinse with water can be, easy. Even after prolonged use, the surfaces like countertops with beautiful new clothes, no maintenance and upkeep.
4, fuel vain
Natural crystalline quartz is typically refractory, its melting point up to 1300 degrees, quartz completely flame made of 94% natural quartz, are not caused by exposure to high temperature combustion, but also with artificial stone countertops unmatched high temperature characteristics.
5, non-toxic and non-radiation
Quartz stone surface is smooth, flat and no scratches retention, dense non-porous material structure allows bacteria nowhere to hide, can be in direct contact with food, safe non-toxic!
Quality quartz crystallization using a selection of natural quartz mineral, its content of more than 99.9% SiO2 and miscellaneous manufacturing process to purify the raw material does not contain any heavy metal impurities may lead to radiation, 94% quartz crystals and other the resin additive makes quartz is no danger of radiation contamination.
- Q: plez help!
- The constituent atoms of a quartz molecule (SiO2) are silicon (Si) and oxygen (O), both of which are light elements all by themselves. When you pair the two oxygen atoms with the silicon atom, you get a molecule made of light elements. So that's a light mass. Now, if you look at the exact atomic structure, a silicon molecule takes up a fair amount of space. Since density is mass over volume... you get a low density mineral: 2.62 g/cm^3
- Q: How many oxygen atoms are in 3.20 g of quartz?

- Q: I found this awesome rock full of quartz but it is also half limestone.

- Q: Does quartz, amethyst, or turquise affect water qality in fish tanks?
- I am also on said mailing list and have seen the TV ads. If you purchase a small electric heater of any kind at all and use it as a portable, personal heater , allowing you to lower the setting of the thermostat for the whole house, you will save some money. If you do not live alone you will also hear some complaints. You can do the equivalent by , er, dressing more warmly and not purchasing anything. To cover all the bases, maybe the Amish are selling knit sweaters too. One of the responses here is just another ad for such much-to-do-about-nothing quartz heaters.
- Q: How can you distinguish between these two minerals by using a piece of paper, a steel knife and a glass bottle?
- Quartz, it is found in felsic igneous rocks(even after years of geology courses I sometimes confuse mafic and felsic, I think I have it right because my memory tool is felSIc, si for silicate minerals. The clay minerals weather away leaving the quartz which is then eroded, as it is transported it weathers and eventually becomes small grains of sand. It is not completely weathered away because it has a pretty high hardness(7, 10 is the max with diamonds at 9) and it is not broken down by rain etc like your micas, feldspars and the other clay minerals which make up felsic rocks.
- Q: If gold can't be made, then how does it get into quartz crystals?
- You're probably interested in whether it is a crystal or a gemstone.....If it looks like a crystal, it is as gemstones need to be cut and polished to be a gem.
- Q: To grind quartz to power, who can recommend me some grinding machine? Many Tks?
- In a piezoelectric crystal, the positive and negative electrical charges are separated, but symmetrically distributed, so that the crystal overall is electrically neutral. Each of these sites forms an electric dipole and dipoles near each other tend to be aligned in regions called Weiss domains. The domains are usually randomly oriented, but can be aligned during poling (not the same as magnetic poling), a process by which a strong electric field is applied across the material, usually at elevated temperatures. When a mechanical stress is applied, this symmetry is disturbed, and the charge asymmetry generates a voltage across the material. For example, a 1 cm cube of quartz with 500 lbf (2 kN) of correctly applied force upon it, can produce a voltage of 12,500 V. Piezoelectric materials also show the opposite effect, called converse piezoelectricity, where the application of an electrical field creates mechanical deformation in the crystal.
- Q: I just noticed a chip on the edge of my quartz countertop, can it be fixed?
- Table tops for end tables or coffee tables would be my first thought. Adhere them to a piece of plywood, build a wooden frame around them, then grout or mortar and seal. Quartz isn't porous, so as long as you pick the right wood/wood sealer you could use it outdoors. Depending on the size, you could also use them to make a mosaic in poured cement for stepping stones, etc for the garden. If they're small enough, they'd also work in place of rocks for potted plants that need drainage.
- Q: I went to one place that suggested that Quartz will fade in sunlight and that it's priced higher than granite. Homedepot's literature shows both to have the same durability.
- Approximately nothing
- Q: does anyone know where i can get a couple of pieces of quartz and copper rods from and a reasonable amount of metal shavings?
- That really depends on what school of practice you are interested in, and what you intend to do with the crystal. If you ask a general question like this, you are likely to get as many varied responses as there are respondents. I don't work with crystals myself, but I am familiar with this bit of common practice. Some people have been known to expose them to the light of the full moon to charge them, and then use them as a sort of magical battery, storing and holding the moonlight for other uses.
