Advatage

Has good thermal conductivity and temperature resistance,melting gold,silver, platinum
and other precious metals and other alloys with high purity graphite crucible,
product high temperature resistance, anti-oxidation corrosion resistance and long service life.

Specifications

•   High purity fine particle graphite
•   Bulk density ≥1.78 g/cm3
•   Electric resistivity ≥9 μ Ω m
•   Bending strength ≥40 Mpa
•   resist compression ≥70 Mpa
•   particle ≤ 43um

Features

• 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.

Utilization

• Graphite crucible is generally used in alloy tool steel smelting and smelting of nonferrous metals and their alloys.
• Graphite crucible can be used in the processing of graphite, graphite crucible, graphite casting crucible tank,pull rods, mold and other graphite products.
• Graphite crucible let the products are more durable than ordinary material products,longer service life, 

Using Tips

•  Stored in dry place,do not get it wet
•  after drying the crucible,don't make it touch with water.
•  Be careful not to give a mechanical impact force,not from a fall or impact
