Alumina Ceramics

Alumina ceramics is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness. High purity alumina ceramics are ideal for environments where resistance to wear and corrosive substances are required. Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential. Alumina ceramic is the material of choice for alumina wear parts. The proven wear and heat resistance of alumina wear parts makes them ideal for the manufacture of wear-resistant components. Alumina has a high melting point, high hardness, although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity. Good chemical stability of alumina leads to high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Testing has shown that the low chemical solubility of alumina ceramics components makes them highly resistant to chemical corrosion. This is what makes high purity alumina the material of choice for components in a wide range of industrial applications. Alumina Ceramics are generally white and the color is derived from either the sintering additives or impurities in the raw materials. We make and supply alumina ceramic grinding media, abrasion ceramic lining and alumina ceramic parts & components. We also supply zirconia ceramics.

Alumina ceramic is a ceramic material based on alumina (Al2O3), which is used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic wave should be used for washing. Alumina ceramic is a widely used ceramic. Because of its superior performance, it has been more and more widely used in modern society, meeting the needs of daily use and special performance.

Application: Wear-resistant material for surfaces of delivery equipment or liquid flowing pipes of petroleum, mining, cement,chemical,steel works and power plants, purposed to effectively resist the impact , corrosion and thermal impact from passing material, reduce abrasion and thereby significantly extends the service life of the equipment. It is the first choice for wear-resistant material for industrial application. It especially endure high temperature. Installation: Either by welding or by sticking with glue according to specific working condition Packing: in cartons plus pallet Product Advantages: Large variety, diverse sizes, small tolerance, accurate dimension

Alumina ceramic lining tile/wear resistant linings/ceramic lined pipe/alumina wear tile/alumina ceramic linings/ceramic lining/abrasion resistant lining/wear protect/alumina ceramic/technical ceramic "wear resistance ceramic" is extreme pure synthetic (alpha) alumina oxide. Today alumina ceramic of 92% purity is the best solution in terms of wear protection performance and material costs. However, other alumina content such 95% and 99% purity is usually custom made by the customers based on each specific conditions, which require either higher purity, impact or hardness for their applications Characteristics Good wear resistant property and long service life; smooth surface, low friction coefficient, low density and light weight; resistant to all kinds of acid, alkali and salt; low thermal expansion coefficient and thermal conductivity, operating temperature can be up to 1000 centi-degree. Application areas Grinding systems Mixer application areas Separator systems Chain conveyor Cyclones Diffusor Pipes Dedusting systems for coal, ash, sinter Ducts Sinter slurry ducts Hooper High temperature cyclones Ventilator housing Salt plants. We are manufacturing most of tiles such as plain ceramic tile, weldable tile with cap and steel retainer for abrasive wear , and cylinderical ceramic, hexgonal tile, small mosaic tile in retangular or in triangle shape for impact wear.
