HITECH CERAMICS Perungudi, Chennai, Tamil Nadu

A ceramic material is an inorganic, non-metallic, often crystalline oxide, nitride or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, weak in shearing and tension. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramics generally can withstand very high temperatures, such as temperatures that range from 1,000 °C to 1,600 °C (1,800 °F to 3,000 °F).     Other Information about Zirconia Do not load too many materials in zirconia crucibles, which can increase the possibility of uneven heating. Slow ramp rate and cooling rate are highly recommended to minimize the thermal shock on crucibles. When increasing the temperature, special attention should be paid on two sensitive temperature periods: not exceeding 3oC/MIN during 100oC ~300oC and 1050oC ~ 1200oC. The rate can be faster in other temperature ranges, but it is recommended to be less than 5oC /MIN. To take the crucible directly out of furnace at high temperature may cause crack. If possible, take it out when the temperature is under 100oC. Zirconia crucibles should not be heated by torch or furnaces that cannot control temperature change rate. The uneven heating can cause crack.

Grinding media are the means used to crush or grind material (cement, mineral, ..) in a mill. Grinding media sorting is performed when the ball load wears out. New grinding balls are then added or full reload is carried out to keep optimum filling degree and hence mill performance.

A crucible is a cup-shaped piece of laboratory equipment used to contain chemical compounds when heating them to very high temperatures. The receptacle is usually made of porcelain or an inert metal. Silica is a white or colorless crystalline compound, occurring abundantly as quartz, sand, flint, agate, and many other minerals and used to manufacture a wide variety of materials, especially glass and concrete.

Quartz crystals are chiral, and exist in two forms, the normal quartz and the high-temperature quartz. The transformation from quartz to beta-quartz takes place abruptly at 573°C (846 K). Since the transformation is accompanied by a significant change in volume, it can easily induce fracturing of ceramics or rocks passing through this temperature limit. Technical Details of Quartz Wares Clear fused quartz glass is a unique material with an unrivalled combination of purity, high temperature resistance, thermal shock resistance, high electrical insulation, optical transparency and chemical inertness.     Chemical Interness Fused quartz does not react with expection of hydrofluoric and at high temperatures phosphoric. There is a slow reaction with caustic alkalies at normal temperatures. There is no reaction with water and steam at moderate temperatures and pressures.More detailed information such as transmission curves and chemical impurity levels are available on request

Fused silica as an industrial raw material is used to make various refractory shapes such as crucibles, trays, shrouds, and rollers for many high-temperature thermal processes including steelmaking, investment casting, and glass manufacture.Refractory shapes made from fused silica have excellent thermal shock resistance and are chemically inert to most elements and compounds, including virtually all acids, regardless of concentration, except hydrofluoric acid, which is very reactive even in fairly low concentrations.Translucent fused-silica tubes are commonly used to sheathe electric elements in room heaters, industrial furnaces, and other similar applications.Quartz glassware is occasionally used in chemistry laboratories when standard borosilicate glass cannot withstand high temperatures; it is more commonly found as a very basic element, such as a tube in a furnace, or as a flask, the elements in direct exposure to the heat.
