Description

Specifications： Bulk density ≥1.82 g/cm3 Electric resistivity ≥9 μ Ω m Bending strength ≥45 Mpa resist compression ≥65 Mpa Ash ≤0.1 % particle ≤43 um（0.043 mm） Size: 7.2 x5.7 x 1.2cm（L x W x H） (other specification size you can see the picture Five ) 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.
