Molecular formula : TIO2
MW : 79.88
density : 3.84 (20 ° C) (anatase); 4.26 (20 ° C) (rutile)
Melting Point : 1720 (anatase) ; 1640 (rutile) ° C
refractive index : 2.52 (anatase); 2.7 (rutile)
characters : the white powder.
purposes : to be an important feedstock and white pottery glaze. Widely used in metallurgy, paint, ink, plastics, rubber, paper, synthetic fibers, porcelain, insulation, welding electrodes, capacitors, cosmetics, etc. correction fluid.
produced or Source : Chloride from rutile ore into titanium tetrachloride again under high temperature oxidation (chlorination) or ilmenite from the sulfuric acid decomposition and iron after hydrolysis (sulfuric acid) derived.
Note : There are two commodities : First rutile titanium dioxide, 4.26 relative density, refractive index 2.72 and light stability is very strong and suitable for outdoor use; Another type of anatase TiO2, 3.84 relative density, refractive index 2.55 , Light poor, and more for indoor paint.
