Zirconia toughened alumina ceramics (ZTA) are material of white, wear-resistant, corrosion-resistant and good chemical stability. Alumina ceramics have high hardness and zirconia ceramics have good toughness. The most commonly method for toughening alumina ceramics is zirconia toughening. Adding an appropriate amount of zirconia to alumina, the two materials form an excellent composite material with high strength and high toughness, with better physical and chemical properties, and a wider range of applications. ZTA has higher flexural strength, fracture toughness and excellent wear resistance. According to the special requirements of different users, the specific ratio of alumina and zirconia can be adjusted to obtain ZTA with different properties. The performance of zirconia toughened alumina ceramics is better than that of 95 alumina ceramics, and the price is much lower than that of zirconia ceramics; in many working conditions where alumina ceramics are not competent, ZTA shows a better cost performance than zirconia ceramics, and is widely used in mining, machinery, electronics, petroleum, chemical and aerospace,etc.
Features of Inert Ceramic Balls Inert ceramic balls have stable chemical features and a low rate of water absorption, inert ceramic balls can resist high temperatures and high pressure. Inert ceramic balls can also resist the corrosion of acid, alkali and some other organic solvents, inert ceramic balls are able to stand the thermal shock (sharp change of temperature) during the chemical reaction process. The main role of these inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the catalyst of low strength in the reactors (a column or a tower). Inert Ceramic Balls have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process. Applications of Inert Ceramic Balls As refractory bed top plugs and supports in order to protect the catalyst bed from thermal impurities so that the catalyst bed is kept intact in spite of wide pressure variation. Inert Ceramic Ball is widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection, etc. Catalyst Bed Support media are used routinely in the following specific services: Ammonia plants, Hydrotreaters, Bender treaters, Isomerization units, pretreaters and reactors, Molecular sieve units, Diesel hydrotreaters, Naphtha treaters, Fixed bed reformers, Reformer pretreaters, Fluidized pollution control, Hydrocrackers (1st stage), Hydrogen plants. Inert Ceramic Balls are widely used in many fields, including: petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers. Packing By plastic bag, each bag 25kgs net, palletized. By super sacks, each big sacks 1000-1400kgs net, palletized. By steel drum, each drum 300kgs net, palletized.

light duty ceramic sheet and ceramic wear plates offer extremely 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.The low friction, smooth surface prevents material build-up in low inclination installations. The square ceramic tiles make it possible to bend the sheeting which makes it the perfect protection for both con-cave and convex surfaces. The size of the ceramic sheeting can easily be adjusted by bending the sheeting and cutting it in between the ceramic tiles. The sheet is supplied with a bonding layer on the back side to simplify the gluing process and reduce the installation time needed. It results in a high bond strength which ensures that the product is securely attached throughout its wear life :chumshun hexagonal tile and sheet size Ceramic hexagonal tile size Ceramic hexagonal mat (stick on silk /nylon net/paper) size S12xT3mm 300*300 mm 150x150mm S12xT6mm 300*300 S12*T13 mm 300*300 S12*T20 mm 300*300 S12*T24 mm 300*300 S12*T11 mm 300*300 Note: more customized size available :(application industry ) -- mining industry -- Cement industry -- Coal handling industry -- Steel industry -- Port industry -- Power plant :(technical data ) 1) :Chemical Composition: Al2O3 SiO2 CaO MgO Na2O 92~93% 3~6% 1~1.6% 0.2~0.8% 0.1% 2): Physical properties: Specific gravity (g/cc) >3.60 Apparent porosity (%) 0 Flexural Strength (20?, Mpa) 280 Compressive strength (20?, Mpa) 850 Rockwell hardness (HRA) 80 Vickers hardness (hv) 1050 Moh?s hardness (scale) =9 Thermal Expansion (20-800?, x10-6/?) 8 Crystal Size (µm) 1.3~3.0
