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.

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

Wear resistant alumina mosaic plate also named ceramic lining pieces mats consist of small plate glued on acetate silk or other special medium. Alumina mosaic plate offer long wear life in .applications with sliding wear .the thickness and the low weight make these products ideal in applications where weight and space are limiting factors. Chemshun high alumina ceramic mosaics in a variety of sizes and shapes including square and hexagonal shapes . Dimensions range from 500*500mm ,300*300 mm, various plant components can be lined quickly and easily with these mosaic plate .

"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
