Product Description

 

Coarse crystalline tungsten powder

Product introduction:
Purpose:
Used for heavy alloys, electrical contact materials, catalysts, pigments, solid lubricants
Appearance: tungsten powder is dark gray, and tungsten powder for spraying is bright gray.
Application: For large slab, tungsten rhenium thermocouple raw material, contact alloy, etc.
Packaging: iron bucket, polyethylene double layer plastic bag is built in.
Net weight: each barrel weighs 50kg, 100kg and 200kg. Tungsten is a non-ferrous metal and an important strategic metal manufacturing process:
Tungsten powder is made of tungsten oxide and recovered in a four tube muffle furnace or a multi tube furnace, with the particle size ranging from 0.6-30 microns. Mainly divided into coarse, medium and fine particle sizes, silver gray powder, and impurity content is based on national standards. Use of tungsten powder: mainly used for tungsten materials and tungsten metallurgical materials. Tungsten powder is made of tungsten oxide and recovered in a four tube muffle furnace or a multi tube furnace, with the particle size ranging from 0.6-30 microns. Mainly divided into coarse, medium and fine particle sizes, silver gray powder. The impurity content is based on the national standard. The preparation method is hydrogen reconstituted tungsten trioxide or ammonium paratungstate. The process of preparing tungsten powder by hydrogen recovery is generally divided into two stages: the first stage is that tungsten trioxide is recovered to tungsten dioxide at 500~700oC; In the second stage, tungsten dioxide is recovered into tungsten powder at 700~900oC.
