Industry information

Trust for fever everyone not unfamiliar, it is widely used in our life, we know it today to the producing method and steps of silicon nitride fever piece!!!!

 

Production steps:

 

1, cast slurry preparation;

 

2, using stretch film displayed on the stretch slurry flow delay, after being dry, embryo system; Step 3, provide tungsten pulp, the use of tungsten plasma corresponding location of embryo in a plain printed as heat source of tungsten wire, and then another grain embryo alignment button on top, forming element combination of embryo;

 

4, vacuum encapsulation;

 

5, hot isostatic pressing: put the plastic packaging after grain embryo combination in isostatic press in 75 ~ 85 ℃ in the liquid, and combined with 130 ~ 160 atmospheres, micro grain embryo fusion bonding;

 

6, presintering;
 

7, pressure sintering furnace;

 

8, cooling silicon nitride was fever. The present invention process simple, operation easy to control; Using the method of silicon nitride heating tablets, the qualification rate of products is higher, has high thermal conductivity, high thermal efficiency, the silicon nitride and at the same time also has high thermal shock resistance.

 

Above is silicon nitride fever piece of production methods and steps, for silicon nitride fever piece, if you have any questions or want to know more about this aspect of information can get in touch with dear friends!
