【Composition:】99.9% Graphite. Ash content less than 0.1%. Excellent?thermal?conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles.
【Performance】Excellent thermal stability for fast heating and cooling / Well corrosion resistance to strong acid and alkali / Good thermal conductivity properties which highly shorten the melting time and save energy / Great impact resistance performance to ensure the reliability of product quality.
【Size】 Capacity: 1KG gold; Height:88mm; Inner diameter:35mm; Top diameter:58mm; Bottom diameter:47mm
【Application】Melting and casting metals such as Gold, Silver, Brass, Aluminum, Copper, Zinc, Plumbum, etc.
【Attention】Pure graphite crucible can NOT be heating by carbon furnace or charcoal kiln. It will be oxidized and cracked; Pure graphite will start to oxidize at 752 °F （400℃). The withstand temperatures can be 3200 °F if you use Air Electric Furnace. The withstand temperatures can be 5000 °F if you use Vacuum or Gas Protection Furnace.
