Nature
black-gray powder. The relative density of 5.7 ~ 6.7I melting point (1795±20)℃. Soluble in acid, insoluble in water, alcohol, ammonia.
Preparation Method
Cobalt oxalate was prepared by a precipitation reaction between a cobalt nitrate solution and an ammonium oxalate solution. After filtration and washing, cobalt oxide was prepared by roasting an oxalic acid drill.
Use
used in semiconductor industry, electronic ceramics and other fields, can be used as varistor, thermistor, Lightning arrester and picture tube glass shell.
Safety
rat oral LDso:1.70g/kg. Inhalation of cobalt oxide dust can cause acute poisoning, the emergence of bronchial asthma. The maximum allowable concentration in air is 0.5 mg/m3. Staff should be protected. Do not contact with acids. When loading and unloading should be light to prevent packaging damage. When there is a fire, it can be suppressed by water, sand and various kinds of fire extinguisher.
