Zircon - an overview ScienceDirect Topics
The word ‘ zircon ’ is very old; the word in Arabic, zarqun, is said to derive from the original form of the word in Persian zar (‘gold’) and gun (‘colour’).Zircon is an orthosilicate mineral with the formula ZrSiO 4.Its hardness on Moh's scale is 7.5 and it is slowly attacked by hot concentrated sulphuric acid. Its density is 4.6–4.7. Its fracture is uneven and may be

Zircon - an overview ScienceDirect Topics
Zircon is a widely occurring mineral, with the chemical formula ZrSiO 4.It has a tetragonal crystal structure (space group = I4 1 /amd, a = 6.607(1) c = 5.982(1)) that is commonly reflected in the habit of zircon crystals (Fig. 1).Pure ZrSiO 4 is colorless, but trace element impurities can give rise to color. Brownish and “hyacinth” colors are common; the latter
