Platinum Nanopowders for biomedical  Hydrogen and nano-platinum have a synergistic effect that can be used in conjunction with the treatment of oxidant stress disorders; Studies have shown that platinum nano particle-mediated photo-thermal effect in the treatment of bone metastases in nude mice can be a good inhibition of bone tumor growth and osteolytic bone destruction; Lactic acid bio-sensor based on nano - platinum black modification for rapid detection, etc.  2. Platinum Nanopowders as catalyst  Nano platinum are widely applied in catalyst part, Nano-platinum powder has excellent bio-catalytic activity, it can be applied to polymer hydrogenation, reduction and synthesis. Nano platinum also can be used as fuel cell catalyst, due to its high cost, due to its high cost, now some use nano nickle to replace the platinum, and some are looking for ways to improve nano platinum efficiency as catalyst in fuel cells to save cost. Last year Chinese researches have developed a superfine platinum nanowire catalyst on the surface of the zigzag, greatly increasing the surface activity and specific surface area of the fuel cell catalyst, increasing its overall catalytic activity by more than 50 times. 3. Platinum Nanopowders for cosmetics Platinum nanoparticles , due to its strong oxidation resistance Platinum can effectively remove free radicals in the human body. Play the anti-aging effect and at the same time to achieve whitening bright. Platinum Nanopowders can also be used for food preservative, car exhaust purification, etc. Nano platinum do have a lot of amazing functions, we cannot list its amazing functions one by one though.  If you're interstsed in Platinum Nanopowders, please feel free to contact us as more

  • High thermal conductivity ceramic material Aluminum Nitride (ALN)
    High thermal conductivity ceramic material Aluminum Nitride (ALN)
    High thermal conductivity ceramic material Aluminum Nitride (ALN)   HW NANO aluminum nitride, ALN, particle size includes:40-50nm,100-200nm,300-500nm,1-2um,5-10um. Packing: 100g, 500g, 1kg or as needed. Aluminum nitride (AlN) is the only technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. Mutifunctional Aluminum Nitride powder is widely used due to its good properties.   1. Nano Aluminum Nitride has features of high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, good injection molding performance;  2. When used in the manufacture of devices, it can reduce the sintering temperature , improve dimensional stability, the hardness of device and elastic modulus, high dielectric constant and low dielectric loss, good thermal conductivity, oxidation resistance and low thermal expansion coefficient (similar to silicon).  3. For composite materials, the matching with semiconductor silicon is good also the interface compatibility. It can improve the mechanical and thermal conductivity dielectric properties of the composite materials.   The main thermal conductivity applications of Aluminum Nitride (ALN): 1. Thermal conductivity of silicone and thermal conductivity of epoxy resin: ultra high thermal conductivity of nano AlN composite silicone with good thermal conductivity, electrical insulation, wide electrical insulation operating temperature (operating temperature -60 ℃ - 200 ℃), low consistency and good construction performance. Products have reached or exceeded the imported products, because it can replace the same imported products and be widely used in heat transfer medium of electronic devices, which improves work efficiency. Such as CPU and radiator caulking, high-power transistors, thyristor components, diodes, contact with the substrate slit at the heat transfer medium. Nano thermal paste fills IC or the gap between the transistor and the heat sink, increasing the contact area between them to achieve better cooling effect. 2. The application of thermal plastic: Nano Aluminum Nitride powder can significantly improve the thermal conductivity of plastic. The experiment showed that when added 5%-10% to the plastic,it could make the plastic thermal conductivity increase from the original 0.3 to 5. Thermal conductivity increased by 16 times. Compared with the thermal fillers (Alumina or Magnesium Oxide, etc.)in the current market, nano AlN with low addition, can improve the mechanical properties of products and the thermal conductivity is improved more obviously. Currently related application manufacturers have large-scale procurement of nano Aluminum Nitride powder, a new type of nano-thermal plastic will be put into the market.  3. The application of high thermal conductivity silicone rubber: good matching performance with silicon, easy to disperse in the rubber. Not only it doesn't influence the mechanical properties of rubber(experiments have shown that the mechanical properties of rubber also being enhanced),but also can greatly enhance the thermal conductivity of silicone rubber, is now widely used in the filed of the military , aviation and information engineering. 4. Other applications: Nano Aluminum Nitride used in smelting non-ferrous metals and semiconductor materials gallium arsenide crucible, evaporation boat, thermocouple protection tube, high temperature insulation, microwave dielectric materials, high temperature and corrosion-resistant structural ceramics and Transparent aluminum nitride microwave ceramic products, and the current application and PI resin, thermal insulation mica tape, thermal grease, insulating paint and thermal oil. by Corrine
