How to clean the oxide material on the surface of molybdenum
After the high temperature burning, the surface of molybdenum rod will form the dark oxidation material, this oxidation material may be molybdenum dioxide or molybdenum trioxide. If you want to clean out this material, how should you clean it? I will introduce some ways to you in the following.
If you want to clean it, then before cleaning it, you should determine what oxide
material it is on the surface of the molybdenum rod. In general, under normal temperature, molybdenum is stable in air, at 500 degrees, molybdenum can have reaction with oxygen to generate molybdenum trioxide. Because molybdenum trioxide is slightly soluble in hydrochloric acid and is easily soluble in hot concentrated sulfuric acid and nitric acid, and can be dissolved in ammonia water and alkali solution, so it can be rinsed off by the dilute sodium hydroxide solution.
