How to prepare fine tungsten disulfide? Researchers have proposed a simple and feasible preparation method – synthesize tungsten disulfide using tungsten powder and sulfur at high temperature without air. When the amount of sulfur is 1.8 times the theoretical amount, the mixture is vulcanized at low temperature and desulfurized at high temperature to produce fine flake WS2 of FS.S.S 1-2μm.

Preparation of Fine Tungsten Disulfide
In the small test, take an appropriate amount of tungsten powder and reagent sulfur, mix evenly according to a certain ratio, fill it into the reaction tank, evacuate it, and seal the exhaust port. Put the reaction tank into the muffle furnace, heat up according to a certain temperature system, open the exhaust port in the desulfurization stage, after the process is completed, cool down and discharge. When expanding the test, power up and argon gas is used to exhaust the air in the two-tube furnace. When the temperature reaches the set value, the boat with the appropriate amount of mixture is pushed into the furnace at a certain speed. Wherein, the discharge end is also protected by argon gas, and the tail water is absorbed by water.
