Preparation Method for Tungsten Disulfide

The invention relates to the technical field of compound preparation and in particular to a preparation method for tungsten disulfide.

The preparation method comprises the following steps: uniformly mixing tungstic acid with an ammonium trisulfide solution to obtain a mixture; putting the mixture into vulcanization equipment, vacuumizing, and heating in the vulcanization equipment at first stage for 50-70 minutes at the temperature of 650-750 DEG C; heating at second stage for 110-130 minutes at the temperature of 1350-1400 DEG C to obtain tungsten disulfide. According to the preparation method, the process is short, the used equipment is simple, and the environmental pollution is alleviated at the same time.
