Molybdenum Powder: The appearance is dark gray, the color should be uniform, no agglomeration, no visible inclusions.

Appearance: Appearance of gray metal powder, uniform color, no visible mechanical impurities.

Ingredients: Metallic molybdenum in powder state.

Introduction: Molybdenum powder is usually made by using ammonium paramolybdate or calcined MoO3 as raw material and reduced by hydrogen. It is the raw material for the preparation of molybdenum deep processing products by powder metallurgy.

Molybdenum powder is divided into two types: light molybdenum powder (PCC) and molybdenum powder (GCC). The characteristics of molybdenum powder can be artificially controlled color, particle size, surface characteristics, dispersion, rheology, thixotropic and crystal form, etc., and molybdenum powder has high chemical purity, strong chemical inertness and good thermal stability, and is not below 400 degrees Celsius. Will decompose. In addition, the molybdenum powder also has the advantages of low oil absorption rate, low hardness, low abrasion value, non-toxicity, odorlessness, odorlessness and good dispersibility.
