Silicon Nitride (Si3N4) is a man made compound synthesized through several different chemical reaction methods. Parts made of Si3N4 are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. Silicon Nitride Ceramic is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance. The very high quality bodies developed for these demanding high reliability applications are available today and can be used in many severe mechanical, thermal and wear applications.What's more, Silicon Nitride Si3N4 is an electrical insulator and is not wet by nonferrous alloys. Silicon nitride is a rather expensive material, but its performance to cost benefit ratio is excellent in the applications where it can outperform the normally utilized materials with long life and very reliable low maintenance operation.Zirconium oxide (Zirconia) is an extremely tough ceramic with a hardness of >9 Mohs which makes it and excellent material for extreme wear, high temperature and harsh environment applications. Zirconia ceramics have remarkable properties of strength, hardness and wear resistance in addition to withstanding attack from molten metal, organic solvents, acids and alkalis. They can also withstand high temperatures for long periods even under severe mechanical stress. Typical Applications include: volatile chemical solutions transportation, jet and diesel engine components, containers for molten metals, high speed cutting tools, high wear components, transistor insulators, dental implants, bearing balls, pump seals, and ball valves.

Weldable alumina ceramic tiles for coal and other material handling and processing industries. Ceramic linings provide long-lasting solutions to the problems caused by abrasive wear and corrosion in a variety of hostile environments. Alumina ceramic linings will outlast lower grade materials commonly used to line or protect processing and material handling equipment, including Basalt, stainless steel, carbon steel and wear resistant plates, by factors of 3 to 15 times. QMX's wear resistant ceramic tiles can be cut into any shape and are easy to install and maintain. They are suitable for both wet and dry processing applications. Advanced ceramics combine high strength and toughness with extreme hardness to deliver exceptional wear resistance. The ceramic pipe tiles,also cale taper tile or Trapezoidal tile, are used on a range of equipment including pipes, tanks, chutes, pumps, flotation cells, thickeners, launders and feed spouts or chutes.

They are suitable for both wet and dry processing applications. Advanced ceramics combine high strength and toughness with extreme hardness to deliver exceptional wear resistance. Mineral Processing equipment operates in some of the harshest and remote locations. It is crucial to the Mineral Processing industries that this equipment continues to operate efficiently and its lifecycle is maximised to minimise down time. By appropriately protecting equipment from the extreme wear caused by the high speed and flow rates of ore when processed as a slurry ensures better equipment longevity. Slurry is highly abrasive and can not only cause wear damage to wet processing equipment but also with the inclusion of chemicals and heat, there is constant risk of corrosion and dangerous leakage. Wear Protection ceramic Linings are used throughout Mineral Processing to protect the steel surfaces of equipment from wear and corrosion. They are used on a range of equipment including pipes, tanks, chutes, pumps, flotation cells, thickeners, launders and feed spouts or chutes.

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
