Graphite Crucible for Metal Casting 250ml Capacity

High purity (99.9%) heat resistant graphite crucibles with flat bottom. good for use with induction heating, recommended for precious metals casting. Volume: 250ml.

Graphite, often called black lead, can tolerate thermal shock and withstands constant working temperature up to 1500°C or 3600°C (vacuum condition). They are the best electrical conductive material known to man, 4 times of steel, 5 times of copper and 100 times of non-metallic materials. They also have higher thermal conductivity than steel, iron and lead, plus resistant to acid, alkali and organic solvent.
