Production process of silicon carbide products
Two hot pressing processes of SiC products
Silicon carbide products can be produced by hot pressing. There are mainly two different hot pressing processes: thermoplastic pressing and slow diffusion principle.
1 thermoplastic pressing
Silicon carbide materials are related to the plasticity of materials heated violently. This method is to heat the materials to the thermoplastic state and then press them. When thermoplastic pressing, densification is achieved by pressurizing the slurry when it is heated and subjected to severe plastic deformation. Generally, it is to preheat the rough billet, and then put it into the die to apply pressure.
2 slow diffusion
Another hot pressing process of SiC products is to use the slow diffusion sintering principle. Compared with thermoplastic pressing, this method usually needs to be carried out at a higher temperature and takes a longer time. Apply pressure to the powder heated directly in the model for a number of times.
What are the methods of SiC products made of SiC materials?
With silicon carbide as raw material, there are many ways to produce silicon carbide products with special technology, and these products have special properties in the effective field. What are the methods to produce silicon carbide?
1. Recrystallized products made of silicon carbide
2. Two kinds of hot pressing sintering of SiC products
3. Production of light silicon carbide products with silicon carbide materials
The above methods are just a few of them, and there are more ways to burn silicon carbide products, which need to be summarized and developed. Different methods, different fields of use, are looking forward to new methods.
How many kinds of refractories contain silicon carbide?
Due to the special properties of silicon carbide, it is very popular with refractories. As long as silicon carbide does not react with refractories, it can be added to refractories. For example, clay, high aluminum, silicon, graphite and other ingredients are added. Thus, the following four kinds of refractories containing silicon carbide are formed.
1. Which material is silicon carbide product
2. High aluminum silicon carbide products
3. Silicon carbide products
4. Carborundum ink products
