We use special technology to prepare high-purity tungsten and molybdenum porous materials. The total porosity, pore size and distribution characteristics can be flexibly adjusted according to customer requirements. The pore characteristics are as follows:

1. The average pore size of conventional tungsten and molybdenum porous materials is 1-5 m, and the total porosity can be adjusted between 5-40%

2. Specially made tungsten and molybdenum "foam" materials, with bimodal pore size distribution, small pore size of 1-5 m, large pore size can be adjusted between 20-700 m as required, total porosity can be adjusted between 10-75%

Compared with traditional forged tungsten and molybdenum materials, our new materials have the following characteristics:

1. It can replace traditional forged tungsten and molybdenum materials in some application fields, and the processing cost can be greatly reduced by using porous materials;

2. Good thermal and electrical conductivity, the thermal conductivity is about 50% higher than that of steel and nickel alloy;

3. High tensile strength

Good high temperature strength and hardness

5. Good corrosion resistance

Application field

1. Arc chamber of plasma injection machine

2. Scientific application

3. Wafers of semiconductor equipment

Fuel cells

5. High temperature filter or gas purification

6. Atomizers that generate nanoparticles
