Technology Specifications of the Al₂O₃ fiber Felt.

Product Performance & Cost Advantage

(1)   Al₂O₃ fiber combine the specifications of the crystal material and fiber material, the use of temperature is above 1450~1600°C, melting point of 1840°C, far higher than the usual aluminum silicate material with good heat stability resistance, which thermal conductivity is ordinary bricks’ 1/6, its density is only 1/25, energy-saving rate of 15-45%.

(2)   Al2O3 fiber, it has low thermal conductivity, heat capacity and thermal shrinkage. It has good chemical stability, can be used in an acidic environment, an oxidizing atmosphere, reducing atmosphere and vacuum conditions, also has some corrosion resistance in alkaline environment.

Product Application

Al₂O₃ fiber is with high temperature performance, mainly used as insulating refractory in metallurgical furnace and ceramic sintering furnace, or used to do insulation materials Body liner in other high temperature furnace. Because of its small density, good insulation and small heat capacity, it not only reduce the quality of the furnace, but also improve the accuracy of temperature control and energy-saving effect. Al₂O₃ fiber with resin, metal or ceramic composite high-performance composite materials preparation, widely used in aviation, aerospace, military and high-tech fields.

Al2O3 fiber with good chemical resistance, can be used in the field of environmental protection and recycling technology, such as electronic waste incineration equipment, with the years of operation, alumina fibers still showed excellent resistance furnace corrosion of various harmful substances. It can be used ceramic monolith substrate automobile exhaust gas treatment equipment, which is characterized by a stable structure. Al₂O₃ fibers can be used for aluminum pistons, the advantage is smaller expansion temperature rises, a decrease of approximately 25% coefficient of expansion than pure metal, so a good fit between the piston and the cylinder, which can save fuel. Since the good wettability of Al₂O₃ fiber and metal matrix ,and small interfacial reaction, mechanical properties of composite materials, wear resistance and hardness are improved. Al₂O₃ fiber reinforced metal

matrix composite materials have been in the automotive piston groove and rotating compressor blades in gas applications, it can reduce vehicle exhaust emissions in the automotive industry, thus contributing to promoting environmental protection.
