MOLECULAR FORMULA : CO2O3-CoO
CAS NO.:1307-96-6
Cobalt Tetroxide
MOLECULAR FORMULA : CO2O3·CoO
PROPERTY:black and grey powder,no smell and no sapor,can be solved slowly in hot muriatic acid and vitriol,it becomes when exposed in air ,but can't hydrate,not solove in water,when heated to 950 centigrade,it turns into CoO2.
USE:used as oxidizer,oil paint,pottery and enamel material;cobalt catalyzer;
PACKING:packed in metal pail and sealed inside by cohesion ethene,net weight is 50kilogram per bucket;packed in plastica calcium box and sealed inside by cohesion ethene,net weight is 25 kilogram per box.
60%, 72% and 74% available, widely used in ceramics, pottery and enamels as blue pigment, also used as oxidizer, oil paint, etc.
