Description of Silicon Carbide Crucible
Silicon Carbide Crucible is a high-temp container made of high-purity silicon carbide via high-temp sintering. With excellent thermal conductivity and shock resistance, it withstands >1600℃, resists molten metal corrosion, and offers strong chemical stability. Widely used in metallurgy, semiconductors, and photovoltaics for smelting precious metals/rare earths and crystal growth, it ensures efficient heat transfer and long service life.

Sizes&Types of KERUI Silicon Carbide Crucible
Based on customer needs, we offer a variety of standard and customized crucibles, including basin or bowl shapes, “TP” shape, bilge shape, spouted or spouted basin shapes, and cylindrical shaped crucibles. We also provide various pouring lips and spouts.
Please Note: that our graphite crucibles are molded using a steel inner mold and an outer rubber mold. As a result, the exterior surface may not be perfectly smooth, while the interior surface is smooth.
Features of Silicon Carbide Crucible
Silicon Carbide Crucible has multiple characteristics: it is made of high-purity silicon carbide as raw material and sintered at high temperature. It can withstand high temperatures above 1600℃, has strong thermal shock resistance, and is not easy to crack due to temperature difference. It has high thermal conductivity and can transfer heat quickly and evenly. It has excellent chemical stability and is resistant to corrosion by molten metals and acids and alkalis. It is wear-resistant and durable, and has a long service life.
Application of Silicon Carbide Crucible
Silicon carbide graphite crucibles serve for melting non-ferrous metals and diverse materials like gold, silver, copper, aluminum, lead, zinc, steel, alloys, ceramics, etc. Applicable in multiple furnaces, they are suitable for metal melting furnaces, stainless steel foundries, coke ovens, coal furnaces and the so on.
