Well thermal stability: according to the using conditions of graphite crucible snap heat and cold.
Well corrosion resistance, impact resistance performance, to ensure the reliability of product quality.
Well resistance to strong acid, strong alkali.
Good heat transfer performance of graphite crucible: for greatly shorten the melting time and save energy.
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.
Long service life.
