manganese powder

Submitted by admin on Thu, 07/18/2019 - 02:44

Metal powders are prepared by electrolysis  atomization and ball milling. All of them are physical changes, so electrolytic manganese is manganese powder.Electrolytic manganese metal is the main material for manufacturing manganese trioxide. In addition, because of its high purity and low impurity, it is an important alloy element for producing stainless steel, high strength low alloy steel, Al-Mn alloy, copper-manganese alloy, etc.

Nickel powder

Submitted by admin on Thu, 07/18/2019 - 02:35

Nickel powder is also divided into carbonyl nickel powder, uniform color, no caking and reunion, no visible inclusions. It is mainly used for coatings and plastics as conductive pigments to shield electromagnetic interference and radio frequency interference, for various high gloss decorative paints and plastics, instead of aluminium powder as anticorrosive paint in water system, etc.

what is Tungsten powder

Submitted by admin on Wed, 07/17/2019 - 02:19

Tungsten powder-like metallic tungsten is a metallic luster gray-black metal (body-centered cubic crystallization). It is the raw material for preparing tungsten processing materials, tungsten alloys and tungsten products.Tungsten powder is used as a raw material for the preparation of tungsten processing materials, tungsten alloys and tungsten products.

Fe-Si-Al alloy is an alloy powder of 85% Fe, 9% Si and 6% Al, which is processed by special process and pressed into ring or E-type magnetic powder cores. It is commonly called Kool M_ u magnetic powder cores or Sendust  powder  in the market.

The main application of nanometer iron oxide

Submitted by admin on Tue, 07/16/2019 - 02:03

Nanometer iron oxide is a multifunctional material. When the size of iron oxide particles is small to nanometer scale (1-100 nm), the number of surface atoms, specific surface area and surface energy of iron oxide particles increase sharply with the decrease of particle size, which shows the characteristics of small size effect, quantum size effect, surface effect and macroscopic quantum tunnel effect.

Beryllium sulfate
