With the advancement of science and technology, the use of ceramic materials is becoming more and more widespread. Here we will focus on the characteristics and differences between traditional ceramics and advanced ceramics.
1. Different raw materials
Traditional ceramics use natural minerals as raw materials, mainly natural silicate minerals, such as porcelain stone, clay, etc.feldspar、QuartzSand, etc.
Advanced ceramics are mainly based on artificially refined synthetic raw materials, expanding from traditional clay raw materials to chemical raw materials, synthetic minerals, and even non-silicate and non-oxide materials raw material. Our common ones include: alumina ceramics, zirconia ceramics, silicon nitride ceramics, etc.
2. Different ingredients
The composition of traditional ceramics is determined by the composition of clay, so ceramics from different origins and kilns have different textures.
The raw materials of advanced ceramics are compounds, the composition is determined by artificial proportions, and the quality of its properties is determined by the purity of the raw materials and the process.
3. Different processing techniques
Traditional ceramics are made by traditional processes such as crushing, grinding, blending, shaping, drying, and calcining Become. Mainly grouting and plastic molding, the sintering temperature is generally below 1350 degrees Celsius, the fuel is mainly kerosene gas, and precise temperature control is not required. Generally no processing is required.
Advanced ceramics adopt precision-controlled advanced processes Sintered, structural ceramics require more than 1600 degrees Celsius, and functional ceramics require precise temperature control. Advanced methods such as isostatic pressing, injection molding, vacuum sintering, hot pressing, and reaction sintering are required. Polishing and other processing techniques.

4. Performance differences
Traditional ceramics focus on appearance, such as ceramic ornaments.
Advanced ceramics are mainly based on intrinsic quality and exhibit specific physical and chemical properties. Have different special properties and functions, such as high strength, high hardness, corrosion resistance, conductivity,Insulation and special functions in magnetism, electricity, light, sound, and bioengineering.
5. Different application fields
Traditional ceramics are mostly used for daily and architectural purposes.
Advanced ceramics are widely used in petroleum, chemicals, steel, electronics, textiles, automobiles, aerospace, nuclear industry and cutting-edge technology fields. Common The products include: insulating ceramics, wear-resistant ceramics, semiconductor ceramics, ceramic tubes, ceramic rods, ceramic sheets, ceramic plates, ceramic plungers, ceramic pump valves, etc.
