What are the uses of silicon carbide sheets?

Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. Silicon carbide rough materials can already be supplied in large quantities and cannot be considered high-tech products. However, the application of nano-scale silicon carbide powder with extremely high technical content cannot form economies of scale in a short time.

(1) As an abrasive, it can be used to make abrasive tools, such as grinding wheels, whetstones, grinding heads, sand tiles, etc.

(2) As metallurgical deoxidizer and high temperature resistant material.

(3) High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.

Main uses: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.

Used in semiconductors, lightning rods, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic membranes, cutting tools, heating elements, nuclear fuel , jewelry, steel, protective gear, catalyst carrier and other fields.

The "three-resistant" material uses silicon carbide to have the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity, and impact resistance. On the one hand, silicon carbide can be used in various smelting furnace linings, high-temperature furnace components, silicon carbide plates, linings, etc. Supports, saggers, silicon carbide crucibles, etc.

On the other hand, it can be used as high-temperature indirect heating materials in the non-ferrous metal smelting industry, such as vertical tank distillation furnaces, distillation furnace trays, aluminum electrolytic cells, copper melting furnace linings, arc plates for zinc powder furnaces, thermocouple protection tubes, etc. ; Used to make advanced silicon carbide ceramic materials that are wear-resistant, corrosion-resistant, and high-temperature resistant; and can also be used to make rocket nozzles, gas turbine blades, etc. In addition, silicon carbide is also one of the ideal materials for solar water heaters on highways, aviation runways, etc.

Silicon carbide plate service life

The service life of silicon carbide plates largely depends on the rationality of the silicon carbide production process and whether the production choice is reasonable. When making sanitary ceramics, high-voltage electromagnetic and other products, the scaffolding on the kiln car needs to bear a heavy load. Therefore, the strength of silicon carbide products is of great significance. According to the thermal stress during baking, it is better to use dense silicon carbide material with strong oxidation resistance.

According to relevant information, many industrial ceramic countries in the United States use silicon carbide materials as the main pillars and flat plates of scaffolds. The thickness of the silicon carbide plates used in production is 25-30mm, and the effect is quite good when used for baking. Of course, the price of silicon carbide boards will be more expensive than clay bricks, but the number of times silicon carbide is used is much higher than that of clay bricks and high alumina bricks, which is good from the economic effect of use.

In the market, although the price of silicon carbide is slightly higher than other high-temperature resistant materials, according to detailed understanding, silicon carbide material has very unique properties, high high-temperature strength, high thermal stability of silicon carbide, and at the same time, silicon carbide has very unique properties. High conductivity and some high-quality features of silicon carbide play a decisive role in extending the life of silicon carbide plates.

Therefore, silicon carbide plates have a long service life. Silicon carbide recycling is quite feasible!
