Reade Advanced Materials offers:
Olivine
Synonyms: Magnesium iron silicate.
It is sometimes inaccurately referred to as forsterite.
Forsterite is pure magnesium silicate.
Designations:
Chemical Name: Olivine
Chemical Formula (Approx.): (MgFe)2SiO4
General Description:
A naturally occurring mineral composed of a solid solution of magnesium ortho silicate, (forsterite, Mg2SiO4) and iron ortho silicate (fayalite, Fe2SiO4). Olivine crystals are angular with sharp edges. the product is hard, dense and heavy. It has good insulating values due to a low heat conductivity. It is essentially hydration-free. It has a high refractoriness level ~1760 deg. C. It is essentially inert and has high chemical and mineralogical stability .
Nominal Chemistry Available:
MgO= 45% to 49%, SiO2= 39% to 42%, FeO= 6% to 8%, CaO= 0.2% to 0.3%, Cr= 0.1% to 0.4%, Ni= 0.1% to 0.3%, Al2O3= 0.2% to 0.8% and Trace Elements= 0.3% to 0.5%
