Neodymium oxide is mainly used as a colorant for glass and ceramics. The raw material for manufacturing metal neodymium and the raw material for strong magnetic neodymium iron boron. Adding 1.5% to 2.5% nanometer neodymium oxide in magnesium alloy or aluminum alloy can improve the high-temperature performance and gas of the alloy. Tightness and corrosion resistance, widely used as aerospace materials. In addition, nano yttrium aluminum garnet doped with nano neodymium oxide produces a short-wave laser beam, which is widely used in the industry for welding and cutting thin materials with a thickness of less than 10 mm. In medical treatment, nano yttrium aluminum garnet laser doped with nano neodymium oxide is used instead of scalpel to remove surgical or disinfect wounds. Nano neodymium oxide is also used for the coloring of glass

  With the continuous advancement of science and technology, the rapid development of electronics, aerospace and aviation, especially communication technology, electronic components are constantly developing from discrete components to high-power, integration and modularization, so more heat will inevitably be generated during operation. At the same time, due to the more complicated use occasions and working conditions, the requirements for the thermal conductivity of the materials are getting higher and higher. Although traditional metal heat conduction has high thermal conductivity, it has its fatal shortcoming, that is, poor insulation. Polymer composite materials can overcome the above shortcomings and are widely used in various industrial heat conduction occasions. Thermally conductive composite materials are prepared by adding high thermal conductivity fillers to organic and polymer materials (body thermal conductive materials). Because organic polymer materials have low thermal

  Overview of arsenic sulfide As2S2 Arsenic sulfide  is an inorganic compound with the chemical formula As2S3, also known as arsenic sulfide.

  Overview of Aluminum Nitride AlN Ceramic Microspheres Aluminum nitride , a covalent bond compound, is an atomic crystal, belonging to diamond-like nitride, hexagonal crystal system, wurtzite type crystal structure, non-toxic, white or off-white. Ceramic spherical aluminum nitride was first synthesized in 1877. In the 1980s, AlN ceramic microspheres, as ceramic insulators, were widely used in the field of microelectronics due to their high heat transfer. Unlike beryllium oxide, AlN ceramic microspheres are non-toxic. Ceramic spherical aluminum nitride is treated with metal and can be used as a substitute for aluminum oxide and beryllium oxide in a large number of electronic instruments. Spherical ceramic aluminum nitride can be made by reducing aluminum oxide and carbon or directly nitriding metal aluminum. Aluminum nitride ceramic microspheres are a material connected by covalent bonds. It has a hexagonal crystal structure with the same shape as zinc sulfide and wurtzite. Industrial
