Silicon carbide, also known as moissanite, is a material smelted at high temperatures in an electric cathode furnace. Such substances also exist in nature and 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.

Silicon carbide size sand is also called silicon carbide grit. Silicon carbide grit is generally divided into 8#-320#. The larger the model, the finer the size. If it is larger than 320#, it is generally called silicon carbide powder.

Silicon carbide grit is divided into two types: green and black. It is an ideal abrasive and is widely used in the abrasives industry. It is mainly used in making grinding wheels, cutting discs, etc.

Here's a look at five basic uses for this material.

Non-ferrous metal smelting

By utilizing the characteristics of silicon carbide such as high humidity resistance, good thermal conductivity, impact resistance, and high strength, it can achieve better results by indirectly heating materials at high temperatures. Such as the lining of copper melting furnace, distillation furnace tray, zinc powder furnace curved plate, aluminum electrolytic cell, etc.

Metallurgical mineral processing industry

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

Building materials, ceramics and grinding wheel industry

Using the characteristics of moissanite such as high temperature resistance and high thermal conductivity, thin plate kiln furniture can be manufactured. It can not only increase the capacity of the 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 the ceramic glaze Ideal indirect material for baking and sintering.

Applications in 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 improve productivity. It is also very suitable to be placed in the discharge pipeline used in mine dressing plants.

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 cells have also occupied a certain position in the market share. They are used in the development of power generation efficiency in battery technology. At present, It is also a market trend.

In the future, the main applications of silicon carbide may also focus on circuit components, semiconductors, structural materials, clutches, nuclear fuel, cutting tools and other fields. And with the improvement of recycling technology, it is also possible to realize the recycling of some finished products.
