Ash content less than 0.1%, to ensure the precious metals in smelting is not contaminated. In high-temperature using process, it got small thermal expansion coefficient. And certain strain resistance to the thermal shock, quenching. Graphite crucible let the products are more durable than ordinary material products longer service life, able to withstand more than 2000 ℃ high temperature.
