Ceramics are the oldest material and the first chemically derived product obtained by humans to conquer nature. It appears much earlier than metal materials and is one of the symbols of human civilization. Product categories: ceramic plungers, ceramic pump cores, ceramic valve cores, ceramic pistons, ceramic bushings, ceramic suction cups, microporous ceramics, etc.; Alumina, zirconia, silicon nitride, silicon carbide. It is also an important research object in the history of human civilization.
1. Traditional Ceramics VS Advanced Ceramics: Raw Materials
Traditional ceramics are made from natural minerals, mainly natural silicate minerals such as porcelain stone, clay, feldspar, quartz sand and so on. Advanced ceramics are mainly made of artificially refined synthetic raw materials, expanding from traditional clay raw materials to chemical raw materials, synthetic minerals, and even non-silicate and non-oxide raw materials.
2. Traditional Ceramics VS Advanced Ceramics: Ingredients
The composition of traditional ceramics is determined by the composition of the clay, so ceramics of different origins and kiln have different textures. The raw materials of advanced ceramics are compounds, and the composition is determined by artificial ratio. The quality of the raw materials is determined by the purity and process of the raw materials.
3. Traditional ceramic VS advanced ceramics: craft
Traditional ceramics are made by traditional techniques such as crushing, grinding, blending, shaping, drying, and calcining. Grouting and plastic molding are the main ones. The sintering temperature is generally below 1350 degrees Celsius. The fuel is mainly coal and oil, and there is no need for precise temperature control. Generally no processing is required. Advanced ceramics are sintered by advanced technology with precise control. The structural ceramics need to be above 1600 degrees Celsius, and the functional ceramics need precise temperature control. Advanced methods such as isostatic pressing, injection molding, vapor deposition, vacuum sintering, hot pressing, and reaction sintering. Processes such as cutting, punching, grinding and polishing are required.
4. Traditional Ceramics vs Advanced Ceramics: Performance
Traditional ceramics are mainly based on appearance. Advanced ceramics are characterized by intrinsic quality and exhibit specific physicochemical properties. It has different special properties and functions, such as high strength, high hardness, corrosion resistance, electrical conductivity, insulation and special functions in various fields of magnetism, electricity, light, sound and bioengineering.
5. Traditional Ceramics VS Advanced Ceramics: Products
Traditional ceramics are divided into daily ceramics, art ceramics, living ceramics, and industrial ceramics. Advanced ceramics are divided into functional ceramics and structural ceramics. Oxide ceramics: alumina ceramics, zirconia ceramics, mullite ceramics, etc.; nitride ceramics: silicon nitride ceramics, aluminum nitride ceramics, boron nitride ceramics, etc.; carbide ceramics: silicon carbide ceramics, titanium carbide ceramics, Boron carbide ceramics, etc.; boride ceramics: titanium boride ceramics, zirconium boride ceramics, and the like.
6. Traditional Ceramics vs Advanced Ceramics: Applications
Traditional ceramics are often used for everyday and architectural purposes. Advanced ceramics are used in a wide range of applications in the petroleum, chemical, steel, electronics, textile, automotive, aerospace, nuclear, and cutting-edge technologies.
