【Attention】Only for ELECTRIC / Vacuum / Gas Protection Furnace. Pure graphite crucible can NOT be heating by Carbon 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 Protect
【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 / 3.46inch; Inner diameter:35mm / 1.38inch; Top diameter:58mm / 2.28inch; Bottom diameter:47mm / 1.85inch
【Application】Melting and casting metals such as Gold, Silver, Brass, Aluminum, Copper, Zinc, Plumbum, etc.
【Composition:】99.9% Graphite. Ash content less than 0.1%. Excellent?thermal?conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles.
