White Tourmaline powder for sell

Submitted by admin on Mon, 01/21/2019 - 09:00

Tourmaline powder is a great material because the smaller the tourmaline particles are, the higher the performance is. Tourmaline powder is made from high quality Brazilian tourmaline.The white color is good for light color products.You can mix Tourmaline powder with cosmetic products.You can put Tourmaline powder into the bathtub to enjoy tourmaline bathing. Tourmaline water, which contains minerals, is gentle to the skin. You can use this powder as a material of negative ion/tourmaline products.

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.
