Characteristics and uses of alumina powder

Today, the production process of alumina powder is high, can produce less than 1 micron alumina powder. Such a fine alumina powder exactly how the features and use it?
  In general, the alumina powder is filtered out through layers of deep processing and the process characteristics. Specifically, alumina powder has the following characteristics:
  (1) high filling
  The high degree of particle spherical, particle size distribution width, rubber, plastic, high-density padding, available low viscosity, good fluidity mixture. Add to a variety of acrylic resin, polyurethane resin, epoxy resin, melamine resin. marble mining equipment
  (2) high thermal conductivity
  Fill its high density compared with the crystalline silicon powder obtained high thermal conductivity, good heat dissipation mixture.
  (3) low wear resistance bauxite ore crusher
  Its appearance is spherical, greatly reduces wear and tear of mixing machines, molding machines and molds and other equipment, extend the useful life of equipment.
The main purpose of the alumina powder: heat sink, greece ore crusher machine cooling the substrate with a filler (MC substrate), thermal grease, phase change film; semiconductor packaging resin with filler; a mixture of silicone thermal binder agent with the filler; ceramic filter . Alumina powder can also do a variety of glass coating materials, precious stones, precision instruments, materials and so on.
