Introduction of five major uses of silicon carbide

Date: 08-01-2023
Silicon carbide, also known as moissanite, is a material smelted at high temperature in an electric cathode furnace. Such substances also exist in nature, which are very rare (such as moissanite). Because of its stable chemical properties, good wear resistance, and high thermal conductivity, it is widely used in various production and living fields such as electrical, telecommunications, and aerospace. Here are five basic uses for this material.

1. Non-ferrous metal smelting

Utilizing the high humidity resistance, good thermal conductivity, impact resistance, and high strength of silicon carbide, it can obtain better results by indirect heating of materials at high temperatures. Such as lining of copper melting furnace, distillation furnace tray, zinc powder furnace arc plate, aluminum electrolytic cell, etc.

2. Metallurgical mineral processing industry

The hardness of moissanite is actually second only to diamond, and it has strong wear resistance, which is more than 5 times the service life of cast iron and rubber. It is also an ideal material for aviation runways.

3. Building materials ceramics and grinding wheel industry

Utilizing the characteristics of high temperature resistance and high heat conduction system of moissanite, thin-plate kiln furniture can be manufactured, which can not only increase the capacity of kiln furniture, but also greatly improve the product quality of the kiln, and help shorten the production cycle. Silicon carbide can be said to be a ceramic glaze. Ideal indirect material for baking and sintering.

4, the application of energy saving

With good stability and thermal conductivity, it can be used as a heat exchanger, reducing fuel consumption by more than 20% for enterprises, and can also greatly increase productivity. It is also very suitable to be placed inside the discharge pipeline used in the mine dressing plant.

5. Applications in new fields

In recent years, the technology research and development of silicon carbide has shown an accelerated trend. For example, the solar photovoltaic industry is in a period of rapid growth, and crystalline silicon batteries also occupy a certain position in the market share. It is used for the development of power generation efficiency in battery technology. At present It is also a market trend.

In the future, the main application of silicon carbide may also be concentrated in the fields of circuit components, semiconductors, structural materials, clutches, nuclear fuels, and cutting tools. And with the improvement of recycling technology, it is also possible to realize the recycling of some finished products.
