Nano gold colloids with good stability

Our client said Nano colloidal gold and gold nanoparticles of Hongwu are unrivaled – we found that your company the best that we could work with.”

Colloid gold solution possesses unique properties such as good optical characteristics, biocompatibility, and catalytic activity. 

Hongwu brand Spiny spheroids nickel powder(<1um, 99%) has a wide range of applications in electronic materials, conductive materials, catalysis, magnetic recording materials, polymers and self-lubricating materials.

Precious Metal Pt Platinum Nanoparticles is generally available for 20nm with purity 99.95%. Sizes can be adjustable to 1um. Nano Pt aqueous dispersion can be customized also. Pt nanopowders are widely used in the fields of catalyst, purification, electronic, etc..

Hongwu supplies Chemical Plating Silver plated Copper fine powders  with different shapes, flake, near-spherical, dendritic, and adjustable size from 1-15um and Ag ratio 5%-35%. Silver coated copper powder is mostly used for conductive, EMI shielding application.

Silicon Carbide Whisker shape was the cubic type same as the diamond and have the characteristic of the antiwear use to the ceramics produce.

Among the dental ceramics, nano zirconia has emerged as a versatile and promising material.

oleophilic Silicon Dioxide Nanoparticles have competitive price in bulk.

Nano grade copper particles is available in 20nm,40nm,70nm or more bigger,widely used in sintering additives.

Nano stainless steel 316L powder, 70nm, 150nm, widely used as metal ink.

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.
