Starting from silicon carbide ceramics and silicate ceramics, this article analyzes their structure, performance characteristics and their application in the industrial field, so let's take a look at their differences.
Structural Features
The structure of silicon carbide ceramics has a high degree of crystallization and uniformity, and has the characteristics of high hardness, high strength, high heat resistance, and high corrosion resistance.
The structure of silicate ceramics is composed of silicate crystals and glass phases. The crystal structure is mostly tetrahedron and octahedron, and has a high degree of crystal order. Due to its high melting point, sintered silicate ceramics have high density and high strength.
From a structural point of view, they all have the characteristic of high strength.
Performance Features
Silicon carbide ceramics have extremely high heat resistance and can be used in high temperature environments up to 1800°C; at the same time, they have excellent corrosion resistance and can withstand corrosive media such as acids and alkalis; they also have extremely high hardness and wear resistance It can be used for a long time under harsh friction conditions.
Silicate ceramics have good heat resistance, corrosion resistance and wear resistance. Silicate ceramics exhibit excellent performance in high temperature and corrosive environments, and their thermal stability can reach above 1500 °C. At the same time, silicate ceramics also have good insulation properties and chemical stability.
From the performance point of view, both have heat resistance, corrosion resistance and wear resistance, but the performance of silicon carbide ceramics is even better.
Applications in Industry
