As I understand, cheap graphite crucible only made from graphite and binder, unlike good quality graphite crucible like Salamander which is made from graphite, carbide silicon and fire clay.
Graphite which used in graphite crucible is made from calcined coke, which itself is a reduction agent since its formula is C element, so does graphite crucible always reacts with oxides and reduce them? So metal oxides short life the crucible?
