  • Platinum Black Catalyst Platinum Nanopowders

    Customized Metal Platinum Black Catalyst Platinum Nanopowders Platinum is one of noble metals, it is one of the best catalyst and antioxidants, nano platinum ( Pt ) with small particles size, strong, safe, stable, reliable, environmentally friendly, non-toxic, tasteless, harmless, can be widely used in biomedical, Catalytic industry, cosmetic etc. 1. 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 hwnano@xuzhounano.com. more

Application of tungsten carbide cobalt powder:

Coercive force of tungsten-cobalt alloy Because the binder phase in cemented carbide is ferromagnetic material, the alloy has certain magnetic properties, and the coercive force can be used to control the structure of the alloy. It is an internal control finger for tungsten steel manufacturers. . The coercive force of WC-Co alloy is mainly related to the drilling content and its dispersion, and increases with the decrease of cobalt content. When the amount of cobalt is constant, the degree of dispersion of the cobalt phase increases as the tungsten carbide grains become finer, so that the coercive force also increases. On the contrary, the coercive force is lowered. Therefore, under the same conditions, the coercive force can be used as a parameter to indirectly measure the grain size of tungsten carbide in the alloy: in the alloy of normal structure, as the carbon content decreases, the tungsten content in the drilled phase increases. When the cobalt phase is greatly strengthened, the coercive force is increased. Therefore, the larger the cooling rate at the time of sintering, the larger the coercive force.
Since tungsten carbide has a high modulus of elasticity value, the WC-Co alloy also has a high elastic grinding amount. As the cobalt content in the alloy increases, the elastic modulus decreases; the grain size of tungsten carbide in the alloy has no significant effect on the elastic modulus. As the temperature of use increases, the modulus of elasticity of the alloy decreases.
