Graphite box (graphite boat) itself is a carrier, we can put the raw materials and parts we need to locate or finalize the design together in which high temperature sintering molding. Graphite box is made of artificial graphite by mechanical processing. So sometimes it’s called a graphite box, sometimes it’s called a graphite boat. The graphite box is mainly used in various vacuum resistance furnaces, induction furnaces, sintering furnaces, brazing furnaces, ion nitridation furnaces, tantalum niobium smelting furnaces, vacuum quenching furnaces, etc.
