WeiTai Energy Technology Co., Ltd. is a leading supplier specializing in wafer and advanced semiconductor consumables. We are dedicated to providing high-quality, reliable, and innovative products to semiconductor manufacturing, photovoltaic industry and other related fields.
Our product line includes SiC/TaC coated graphite products and ceramic products, encompassing various materials such as silicon carbide, silicon nitride, and aluminum oxide and etc.
As a trusted supplier, we understand the importance of consumables in the manufacturing process, and we are committed to delivering products that meet the highest quality standards to fulfill our customers’ needs.
Graphite crucible is mainly used to smelt copper, brass, gold, silver, zinc and lead, and other non-ferrous metals and their alloys.
Our graphite crucible are processed with high purity isostatic pressed graphite, which has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to acute heat and acute cooling. It has strong corrosion resistance to acid and alkaline solution and excellent chemical stability. The specific models can be customized with drawings and samples, and the materials are domestic graphite and imported graphite to meet the different needs of customers.
