AI Technical Summary
Tungsten crucibles are prone to volatilization during use, and the temperature gradient and turbulent flow of the melt inside the crucible lead to high costs and unstable quality in gemstone growth.
A novel sintering tungsten tungsten tumbler is designed, comprising a crucible body with an inclined inner wall and a circular arc bottom side structure, combined with front and rear heaters and a modular insulation cover, and optimized thermal field design to improve temperature gradient and natural convection, and reduce volatile emissions.
This approach achieves improved temperature field stability and quality in gemstone growth, reduces production costs, enhances crystal growth uniformity and doping effects, and minimizes equipment investment and volatile matter loss.
