Tell me usage of Zircon?

Question

Zircon is a Mineral sand.

Answer 1

Zircon is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is ZrSiO4. Hafnium is almost always present in quantities ranging from 1 to 4%. The crystal structure of zircon is tetragonal crystal class. The natural color of zircon varies between colorless, yellow-golden, red, brown, and green. Colorless specimens that show gem quality are a popular substitute for diamond; these specimens are also known as "Matura diamond" (but note that cubic zirconia is a completely different synthetic substance with a different chemical composition).

The name derives from the Arabic word zarqun, meaning vermilion, or perhaps from the Persian zargun, meaning golden-colored. These words are corrupted into "jargoon", a term applied to light-colored zircons. Yellow zircon is called hyacinth, from a word of East Indian origin; in the Middle Ages all yellow stones of East Indian origin were called hyacinth, but today this term is restricted to the yellow zircons.

Zircon is regarded as the traditional birthstone for December.

Commercially, zircons are mined for the metal zirconium which is used for abrasive and insulating purposes. It is the source of zirconium oxide, one of the most refractory materials known. Crucibles of ZrO are used to fuse platinum at temperatures in excess of 1755 oC. Zirconium metal is used in nuclear reactors due to its neutron absorption properties. Large specimens are appreciated as gemstones, owing to their high refractive index (zircon has a refractive index of around 1.95, diamond around 2.4). The color of zircons that do not have gem quality can be changed by heat treatment. Depending on the amount of heat applied, colorless, blue and golden-yellow zircons can be made.

PHYSICAL CHARACTERISTICS:
•Color is brown, red, yellow, green, blue, black, and colorless.
•Luster is adamantine.
•Transparency crystals are transparent to translucent.
•Crystal System tetragonal; 4/m 2/m 2/m
•Crystal Habits: dipyramidal and prismatic as discussed above.
•Cleavage indistinct in two directions, prismatic.
•Fracture is uneven
•Hardness is 7.5
•Specific Gravity is 4.6-4.7
•Streak white
•Associated Minerals albite, biotite, garnets, xenotime and monazite.
•Other Characteristics: is sometimes fluorescent and darker crystals may be radioactive due to impurities of rare earth elements. Also index of refraction is 1.92 - 2.01
•Notable Occurances Seiland, Norway; Pakistan; Russia; Bancroft and Sudbury, Ontario, Canada and New Jersey and Colorado, USA.
•Best Field Indicators are crystal habit, hardness, luster and density.

Answer 2

Drugs are bad, I went to rehab for yayo and pills and havn't done either in over 3 years, and frankly I would advise people to STAY AWAY FROM THAT SHIIT. Quitting coke was one of the hardest things I've ever done in my life. Still smoke weed on the reg tho, and eat acid every once in a while....but the real hard stuff I do not reccommend @Latj- Marijuana is not a gateway drug. You could prove this by taking away all other outside stimuli that could affect the thoughts and decisions of the "weed smoker." If I never left my house, and you brought me marijuana every day to smoke, there is no better chance that I would move on to hard drugs than if I had not smoked weed at all. The reason that smoking marijuana can lead to other drugs is because of the process of getting the drugs and the people who you are around you while using them. Chances are someone you would smoke the weed with has already tried some sort of harder drug, or the dealer you buy the weed from has access to harder drugs. And because the people who already smoke weed have done a "drug" then they are more likely to say yes to something else more than someone who has never done a drug because they think it is morally wrong for one reason or another. It's not the weed that leads to other drugs, it is the environment that most weed smokers enter to either smoke the weed or purchase the weed that can lead to other drugs.

Answer 3

In Indian astrology, Zircon is prescribed to propitiate Shukra(Venus). This is supposed to bring wealth and luxury This gem stone is worn on Friday in middle finger in silver ring by chanting "om shun shukrai namah"

Answer 4

Commercial usages of zircon are things such as ammonia removal for fish tanks and it can be used to retard the movement of radionuclides.

Answer 5

It looks like it's used as an ore for zirconium which has industrial applications
