What is the difference between the performance of traditional ceramics and special ceramics ?
Special ceramics, also known as advanced ceramics, is a new type of ceramics in the 21st century. Do you know the characteristics of special ceramics? What is the difference between its performance and traditional ceramics? Let's follow Kezhong Ceramics to see what properties special ceramics have.
Special ceramic parts. Special ceramics refer to ceramics with special mechanical, physical or chemical properties, which are used in various modern industries and cutting-edge science and technology. The raw materials used and the required production process are very different and developed from ordinary ceramics. The country calls it "precision ceramics". Recently, my country's material experts agree that it is better to call it "advanced ceramics".
The performance difference between traditional ceramics and special ceramics :
(1) The preparation process is different
Minerals used in traditional ceramics can be directly used in wet forming after mixing, such as plastic forming of mud and slip casting of slurry. Special ceramics generally use high-purity powders to add organic additives to adapt to dry or wet molding. The sintering temperature of the material is relatively high, ranging from 1200°C to 2200°C according to different materials, and generally needs to be processed after firing. In the process of preparation, we have broken through the traditional ceramic furnace as the main production method, and widely used advanced methods such as vacuum sintering, protective atmosphere sintering, hot pressing, and hot isostatic pressing.
(2) Different raw materials
Traditional ceramics use natural minerals, such as clay, quartz and feldspar, without processing; while special ceramics use synthetic high-quality powder as raw material, breaking through the boundaries of traditional ceramics that use clay as the main raw material. It is based on "selected raw materials".
Due to the differences in the above points, the performance of traditional ceramics and special ceramics is very different. The latter is not only far superior to the former in terms of performance, but also special ceramic materials have found characteristics and uses that traditional ceramic materials do not have.

So what are the characteristics of special ceramics ?
Special ceramics have excellent physical and mechanical properties, high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, thermal shock resistance, and have superior functions in heat, light, sound, electricity, magnetism, chemistry, and biology. These properties far exceed those of modern alloys and polymer materials.
Therefore, it has become the protagonist of the new material revolution, and has extensive application value and potential in petroleum, chemical, steel, electronics, textile, automobile and other industrial fields as well as many technical fields. Such as aerospace, nuclear industry and military industry. Through the introduction of the editor, I have a certain understanding of the performance difference between traditional ceramics and special ceramics. The latter is not only far superior to the former in terms of performance, but also special ceramic materials have found characteristics and uses that traditional ceramic materials do not have.
