High Purity Graphite Crucible—JX-HGC
JX-HGC is machined from high purity graphite and widely used in the gold, silver and other noble metal’s melting. If it’s used in oxygen atmosphere, it will start to be oxygenized when the temperature is higher than 700-800°C. If it’s used in the protective atmosphere, it can stand more than 2000°C.
