Feature: 1. Premium Materials: The main material is graphite. In order not to affect the metal purity during the metal refining process, we control the overall ashes content below 0.1%. 2. Good Thermal Conductivity: Good thermal conductivity, good thermal stability and heat dissipation make it better than ordinary silicon carbide graphite crucible for refining. 3. High Temperature Resistant: It is high temperature resistant and can withstand temperatures of 2000 degrees Celsius without affecting the mold. 4. Corrosion Resistance: Using sophisticated production technology, corrosion resistance, impact resistance, acid and alkali resistance. 5. Uses: It can be used for the experiment and smelting of non ferrous metals such as gold, silver and copper, and can also be used as an ingot mold.
