Special ceramics are ceramics that use highly selected or synthetic raw materials, precisely control the chemical composition, and through technical processing and structural design, with excellent characteristics, also known as advanced ceramics or fine ceramics. Special ceramics can be divided into two types: structural ceramics and functional ceramics. Structural ceramics are mainly structural ceramic materials which used for wear resistance, high strength, high temperature resistance, thermal shock resistance, hardness, high rigidity, low thermal expansion and heat insulation. Functional ceramics include ceramic products and materials which used for electromagnetic functions, optical functions, and bio-chemical functions, as well as nuclear energy ceramics and other functional materials.
General Information• Raw materials: Artificial refined chemical raw materials and synthetic raw materials. Ingredients: The raw materials are pure compounds, which are determined by manual ratio.
• Forming: Mainly static pressure forming, like compression molding, hot die casting, film rolling, casting, etc.
• Firing: Structural ceramics are sintered at a high temperature of about 1600°C. Functional ceramics need to be precisely controlled at the firing temperature. The fuel is mainly electricity, gas, and oil.
• Processing: Often need cutting, drilling, grinding, grinding and polishing.
• Performance: Mainly based on internal quality, often showing temperature resistance, corrosion resistance, abrasion resistance and electrical, optical, thermal, magnetic, sensitive and biological properties.
• Application: Used in aerospace, energy, metallurgy, machinery, transportation, home appliances, etc.

Zirconia (ZrO2) Ceramics
Zirconia ceramics (ZrO2) can obtain yttrium-stabilized zirconia, cerium-stabilized zirconia, and magnesium-stabilized zirconia according to the added stabilizers (Y2O3, CaO2, MgO). Zirconia ceramics have the characteristics of high strength, high hardness, high toughness, wear resistance and corrosion resistance at room temperature, and are widely used in modern industry and life.
Mainly used in grinding media (that is, grinding balls and microspheres of different materials), ceramic bearings, ceramic ferrules and sleeves, engine parts, solid electrolyte materials, metallurgical high-temperature applications, wear-resistant structural parts, biomedical materials and other fields.
Silicon Carbide (SiC) Ceramics
Silicon Carbide ceramics not only has excellent normal temperature mechanical properties, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance etc.), are the best known ceramic materials. Materials have high-temperature strength up to 1600°C, which is the best high-temperature strength material among ceramic materials. The oxidation resistance is also the best among all non-oxide ceramics. Alias emery.
Nitride (Si3N4) Ceramics
Silicon nitride ceramics have high strength, high hardness, high fracture toughness, and excellent properties such as high temperature resistance, wear resistance, corrosion resistance, low thermal expansion coefficient, and good thermal shock resistance. Therefore, it have been applied more and more in modern science and technology and industrial fields such as metallurgy, machinery, energy, automotive, semiconductor and chemical industry.
