In modern industrial production, silicon carbide is widely used. pressureless sintered silicon carbide and reaction sintered silicon carbide are two main preparation methods. These two methods have their own characteristics and are suitable for different use scenarios. This article will introduce in detail the use methods and application scenarios of these two kinds of silicon carbide.

First, let’s look at press-free sintered silicon carbide. Pressureless sintering of silicon carbide is a method by which silicon carbide powder is mixed with other raw materials at high temperatures and then densified by hot pressing or vacuum treatment. This method is characterized by high production efficiency and low cost, but the performance of the product is relatively low. Therefore, non-pressure sintered silicon carbide is mainly suitable for some applications that have low performance requirements but are cost sensitive, such as ceramics, grinding wheels, abrasives and so on.

Next, let’s take a look at reaction sintered silicon carbide. Reaction sintered silicon carbide is a method of achieving densification by mixing silicon carbide powder with other materials at high temperature and then heating them to cause a chemical reaction. The characteristic of this method is that the product has high performance, but the production cost is also high. Therefore, reaction sintered silicon carbide is mainly suitable for some applications that require high performance and are not sensitive to cost, such as high-performance ceramics, high-temperature wear-resistant materials, electronic materials, etc.

Generally speaking, pressureless sintered silicon carbide and reaction sintered silicon carbide have their own advantages and are suitable for different application scenarios. Pressureless sintered silicon carbide is suitable for applications that have low performance requirements but are cost-sensitive; while reaction sintered silicon carbide is suitable for applications that have high performance requirements but are not cost-sensitive. Therefore, when choosing the preparation method of silicon carbide, it is necessary to decide according to the specific application needs.
