SYNTHETIC RUTILE FROM ILMENITE - Entrepreneur India

SYNTHETIC RUTILE FROM ILMENITE. Titanium is relatively abundant in the earth’s crust, which is usually found in igneous and metamorphic rocks as ilmenite (FeTiO3), rutile (TiO2) and titanomagnetite (Fe2TiO4â€"Fe2O4). Ilmenite is a lustrous black to brownish titanium ore, essentially FeTiO3.

High-grade synthetic rutile has been produced in the laboratory from domestic ilmenite concentrates by a new carbonyl process. The ilmenite was first reduced to convert the iron oxides to metal and then treated at temperatures over 100 deg c in high-pressure carbon monoxide (co) to convert the iron to the pentacarbonyl. Rapid carbonylation was achieved in the presence of small quantities of sele
