AI Technical Summary
Technical Problem
In the existing tantalum powder magnesium reduction and deoxidation process, the frame material supporting the crucible is prone to falling off at high temperatures, which leads to increased impurities in the tantalum powder and higher costs.
Method used
High-chromium-nickel austenitic stainless steel is used as the frame base, and tantalum metal coating is wrapped around it. Combined with specific heat treatment and pre-coating treatment steps, a high-temperature resistant and reliable crucible support frame is formed.
Benefits of technology
A crucible that reliably supports the mixing of tantalum and magnesium powders at high temperatures reduces the impact of impurities, lowers costs, and improves the purity of tantalum powder and production efficiency.
