The comparative advantages of four industrial ceramics
Advantages comparison of alumina ceramics and zirconia ceramics, silicon carbide ceramics and silicon nitride ceramics
There are much wear resistant ceramic materials that are well known in the market: silicon carbide, alumina ceramic, zirconia, and silicon nitride. Synthetically consider market needs, Chemshun Ceramics would like to help buyers to analyze the advantages of these materials.
The advantages of silicon carbide are the relatively cheap price, good corrosion resistance, and high strength. The biggest drawback is that it is easily oxidized and difficult to sinter. Wear resistant alumina ceramic is the cheapest, and the preparation process of powder raw materials is also very mature. The latter two have obvious disadvantages in this regard, which is one of the bottlenecks restricting the development of the latter two. Especially silicon nitride, the price is the most expensive.
Although the mechanical properties of silicon nitride and zirconia, such as strength and toughness, are far better than those of alumina, it seems that the cost performance is also appropriate, but in fact there are many problems. In the case of zirconia first, it has a high toughness due to the presence of a stabilizer, but its high toughness is time-sensitive, and its inability to use at high temperatures and room temperature timeliness are seriously hampering the development of zirconia. It is the smallest of the three markets. Silicon nitride, which is also a popular ceramic in the past 20 years, has good comprehensive performances such as wear resistance and thermal shock strength, but the use temperature is lower than that of the other two; its finished product preparation process is also more complicated than aluminum oxide, although The use of zirconia is much better, but it is still inferior to alumina ceramic lining.
