Zircon (Zircon Flour / Zircon Sand (ZrSiO4)

Description:

A course or fine white mineral powder that is naturally occurring, chemically inert and stable to very high temperatures. Insoluble in water, dilute acids and hot concentrated sulfuric acid.

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 the 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”. It is not to be confused with cubic zirconium, a synthetic substance with a completely different chemical composition.
