In the modern industrial field, silicon carbide ceramics are known as the “industrial armor” and have become a key material in extreme environments due to their high strength, high temperature resistance, and corrosion resistance. But what many people don’t know is that the silicon carbide ceramic family actually has multiple members, and different preparation processes give them unique “personalities”. Today we will talk about the most common types ofsilicon carbide ceramicsand reveal the unique advantages of reaction sintered silicon carbide, the core technology of enterprises.
1、 The “Three Brothers” of Silicon Carbide Ceramics
The performance of silicon carbide ceramics largely depends on its preparation process. There are currently three mainstream types:
1. Non pressure sintered silicon carbide
By directly molding silicon carbide powder through high-temperature sintering, it has high density and strong hardness, but the preparation temperature is high and the cost is expensive, making it suitable for small precision components with extremely high performance requirements.
2. Hot pressed sintered silicon carbide
Formed under high temperature and high pressure, it has a dense structure and excellent wear resistance, but the equipment is complex and difficult to produce large-sized or complex shaped components, limiting its application range.
3. Reaction sintered silicon carbide (RBSiC)
By introducing silicon elements into silicon carbide raw materials and using chemical reactions to fill material gaps, the process temperature is low, the cycle is short, and large-sized and irregular parts can be flexibly manufactured. The cost-effectiveness is outstanding, making it the most widely used type of silicon carbide in the industrial field.
2、 Why is reaction sintered silicon carbide more favored?
As a core product of the enterprise, the unique process of reaction sintered silicon carbide (RBSiC) makes it the “preferred material” in many industries. Its advantages can be summarized by three keywords:
1. Strong and durable
The reaction sintering process forms an “interlocking structure” inside the material, which can resist high temperatures of 1350 ℃ and has excellent wear resistance and high temperature resistance – not easily damaged in high wear and high temperature environments, especially suitable for high-temperature scenarios such as kiln accessories and burners.
2. Go into battle with light equipment
Compared to traditional metal materials, reaction sintered silicon carbide has a lower density but can provide the same level of strength, significantly reducing equipment energy consumption. For example, in the photovoltaic industry, lightweight silicon carbide components can significantly improve the operational efficiency of single crystal furnaces.
3. Flexible and versatile
Whether it is semiconductor trays with a diameter of over 2 meters, complex nozzles, sealing rings, or customized shaped parts with different shapes, reaction sintering technology can accurately control the shape and size, solving the manufacturing problem of “large and precise”.
3、 The ‘invisible driving force’ of industrial upgrading
The “figure” of reaction sintered silicon carbide has penetrated into multiple fields, from erosion resistant guide rails in metallurgical furnaces to corrosion-resistant pipelines in chemical equipment. Its existence not only extends the lifespan of equipment, but also helps enterprises achieve energy conservation and consumption reduction – for example, in the field of industrial kilns, the use of silicon carbide kiln furniture can significantly reduce heat loss.
Conclusion
The ‘ability’ of carbide ceramics goes far beyond this. As a pioneer in reaction sintering technology, we continuously optimize the process to maximize the value of this material in extreme environments. If you are looking for industrial solutions that are heat-resistant, impact resistant, and have a long lifespan, you may want to pay attention to more possibilities of silicon carbide ceramics!
