The graphite crucible has good thermal stability, suitable for emergency heat or cold usage condition. Good corrosion resistance and impact resistance. acids resistance and alkalis resistance. The graphite crucible has good thermal conductivity properties,it can greatly shorten the melting for TIME and saved energy. It can melt gold, silver, and other preciou metals and other alloys,with long service life. Graphite tank using high fine grain graphite, high density, not easy adhesion, easy mold release for gold and silver melting after the formation of gold and silver pieces can also be used as graphite crucible melting into non-ferrous metals, test analysis, as the ingot mold and other purposes the capacity is an approximate number= inside Length*Width*Height*0.9 Size: 1kg gold internal size 105x35x20mm Colour:black Material:graphite Package Contents: 1 x Mould Crucible Only the above package content, other products are not included.
