About Aluminum Nitride AlN Ceramic Microsphere:AlN Ceramic Microsphere has high thermal conductivity (340W) and heat transfer performance after secondary laser melting alloying. Very low oxygen content (lt;0.1%), heat preservation and thermal conductivity effect is very obvious. Used in polymer resin, viscosity is not obvious, is currently a better high thermal conductivity insulation filler.Ceramic spherical aluminum nitride was first synthesized in 1877. In the 1980s, AlN Ceramic Microsphere, as a Ceramic insulator, has been widely used in the field of microelectronics due to its high heat transferability. Unlike beryllium oxide, AlN Ceramic Microsphere is non-toxic. Ceramic spherical aluminum nitride is treated with metal and can be used as a substitute for alumina and beryllium oxide in a large number of electronic instruments. Spherical ceramic AlN can be prepared by reducing aluminum oxide and carbon or directly nitriding metal aluminum.AlN Ceramic Microsphere is a kind of material connected by covalent bonds. It has a hexagonal crystal structure with the same shape as zinc sulfide and wurtzite. Industrial-grade materials can only be made by hot pressing and welding. This material is very stable in an inert high-temperature environment. Nanometer is a trusted global Aluminum Nitride AlN Ceramic Microsphere supplier.

Spherical aluminum nitride ceramics were prepared by laser flame melting. The product has the advantages of high purity, uniform particle size distribution, clean surface, high sphericity, no residual impurities, easy dispersion and good compatibility with organisms. Applications of Aluminum Nitride AlN Ceramic Microsphere:1. After the secondary laser melting and spherical alloying, the obtained AlN Ceramic Microsphere has uniform size and good fluidity, which improves the thermal conductivity and insulation of the material;2. After melting, the surface of AlN Ceramic Microsphere is treated with resistance to hydrolysis and oxidation, and the thermal conductivity exists for a long time after addition.3. Ceramic spherical aluminum nitride has good injection molding performance; Used in composite materials, it has a good match with semiconductor silicon and good interface compatibility, which can improve the mechanical properties and thermal conductivity of composite materials;4. Application in high thermal conductivity plastics: Modified AlN Ceramic Microsphere can greatly improve the thermal conductivity of plastics. At present, it is mainly used in PVC plastics, polyurethane plastics, PA plastics, PP plastics, functional plastics, etc.Storage Condition of Aluminum Nitride AlN Ceramic Microsphere:The damp reunion will affect aluminum nitride (AlN) ceramic microsphere dispersion performance and using effects, therefore, aluminum nitride (AlN) ceramic microsphere should be sealed in vacuum packing and stored in a cool and dry room, the aluminum nitride (AlN) ceramic microsphere can not be exposure to air. In addition, the aluminum nitride (AlN) ceramic microsphere should be avoided under stress.Packing & Shipping of Aluminum Nitride AlN Ceramic Microsphere:We have many different kinds of packing which depend on the aluminum nitride (AlN) ceramic microsphere quantity.Aluminum nitride (AlN) ceramic microsphere packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.Aluminum nitride (AlN) ceramic microsphere shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.Aluminum Nitride Microsphere PropertiesOther NamesAluminium nitrideCAS No.24304-00-5Compound FormulaAlNMolecular Weight40.9882AppearanceWhite to pale yellow powderMelting Point2200 °CBoiling Point2517 °C (dec.)Density2.9 to 3.3 g/cm3Solubility in H2ON/AElectrical Resistivity10 to 12 10x Ω-mPoisson’s Ratio0.21 to 0.31Specific Heat780 J/kg-KThermal Conductivity80 to 200 W/m-KThermal Expansion4.2 to 5.4 µm/m-KYoung’s Modulus330 GPaExact Mass40.9846Monoisotopic Mass40.9846 Aluminum Nitride Microsphere Health & Safety InformationRemarksDangerHazard StatementsH314-H335Hazard CodesXiRisk Codes36/37/38Safety Statements26-37/39RTECS NumberN/ATransport InformationN/AWGK Germany3 Inquiry us
