The sintering methods of tungsten you should know
1. Direct sintering method
Direct sintering, also known as vertical melting sintering, is used for sintering small billets. Sintered tungsten rod blanks can be used to produce tungsten rods, tungsten rods, tungsten wires, etc.
2. Indirect sintering method
The indirect sintering method is generally used for the sintering of large tungsten billets and some special tungsten products such as tungsten crucibles, tungsten cylinders, tungsten boats, etc.
3. New sintering furnace
In addition to the above-mentioned industrial-scale sintering methods, some new sintering methods have been developed, such as spark plasma sintering, microwave sintering, pressure sintering, etc.
