Due to the high melting point of tungsten itself, it is difficult for the traditional casting and molding method to be directly applied to the manufacture of crucibles, so the sintering process has become one of the main methods for preparing tungsten crucible. In this paper, we will focus on the sintering process of crucibles, and discuss its process flow, key parameters, technical challenges and optimization directions.

The development of high-end manufacturing industry has put forward higher requirements for the temperature resistance, thermal shock resistance, structural stability and service life of tungsten crucibles. 

Monocrystalline materials occupy a core position in high-tech industries such as semiconductors, optoelectronics, lasers, and aerospace, and their crystal quality directly affects the performance and reliability of terminal devices. 

The manufacturing process of tungsten crucible is complex and the technical requirements are high, mainly including powder preparation, pressing molding, high-temperature sintering and mechanical processing.
