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.
Material: ? 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
Size: ? 25mm x 25mm
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， able to withstand more than 2000 ℃ high temperature
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.
