Manufacturer Platinum Nanoparticles for Sell

Submitted by admin on Tue, 01/15/2019 - 08:45

Platinum nanopowder has a high catalytic activity and is used widely in catalysis, batteries, fuel cells, capacitors and sensors. They are used in the synthesis of counter electrode in dyes sensitized solar cells. Since it is difficult to directly use platinum nanoparticle as the electrode, they are usually surface supported on graphene or multi-walled carbon nanotubes.

The use of Yttrium Oxide Nanopowder / Nanoparticles

Submitted by admin on Tue, 01/15/2019 - 08:29


Yttrium oxide is Y2O3. Yttrium oxide Nanoparticles is an air-stable, white solid substance. Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds. 

Yttrium Oxide Nanopowder / Nanoparticles is the most important yttrium compound and is widely used to make YVO4 europium and Y2O3 europium phosphors that give the red color in color TV picture tubes. 

Electrolytic copper powder suppliers

Submitted by admin on Mon, 01/14/2019 - 09:08


The copper powder is manufactured using an electrolytic process. The powder particles have a unique dendritic shape that offers low apparent density and high specific surface area. Consequently, the powder is widely used in a variety of fields.

This powder features low apparent density, high specific surface area, high purity, good compactibility, good sinterability, and high conductivity. It is used extensively as a raw material in oil-impregnated bearings, sintered machinery parts, carbon brushes, and friction materials.

Application of Aluminum Oxide Nanoparticles Al2O3

Submitted by admin on Fri, 01/11/2019 - 09:22

Aluminum Oxide Nanoparticles Al2O3 is a white powder composed of nanoparticles of alpha-phase aluminum oxide, the naturally-occurring form of aluminum oxide or corundum, the core mineral of rubies and sapphires. Particles of alpha aluminum oxide nanopowder typically range from 40nm to as large as 10um, depending on application, purity standards, and coatings.

Manufacturer supply Strontium Titanate Nanoparticles SrTiO3

Submitted by admin on Fri, 01/11/2019 - 09:11

Strontium titanate is an oxide of strontium and titanium with the chemical formula SrTiO3. At room temperature, it is a centrosymmetric paraelectric material with a perovskite structure. At low temperatures it approaches a ferroelectric phase transition with a very large dielectric constant ~104 but remains paraelectric down to the lowest temperatures measured as a result of quantum fluctuations, making it a quantum paraelectric.
