• [Package]: 1x Graphite Casting Melting Ingot.
• [Multiple Models]: Different Size(you can choose).Composition: 99.95% Graphite. Ash content less than 0.1%. Excellent thermal conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles.
• [Feature]: 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.
• [Warm-Tips]: 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 ¡ãF (400¡æ). They withstand temperatures can be 3200 ¡ãF if you use Air Electric Furnace. They withstand temperatures can be 5000 ¡ãF if you use Vacuum or Gas Protection Furnace. Application Melting and casting metals such as Gold, Silver, Brass, Aluminum, Copper, Zinc, Plumbum, etc.
