What is a tungsten crucible?

Tungsten crucible is mainly used in metallurgical industry, mechanical processing, glass and ceramic industry and other fields. Tungsten crucible is one of the tungsten products, mainly divided into sintering molding, stamping molding, spinning, using rod turning molding, welding forming a variety of, using pure plate, tungsten sheet and pure rod processed by the corresponding process. It can be used in vacuum inert gas below 2600 degrees.

Tungsten is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.

How to clean oxide on the surface of metal molybdenum bar?

The molybdenum rod will form dark oxide on the surface after the high temperature burning of the oxyhydrogen flame. Is it dioxide or molybdenum trioxide? Now it needs to be cleaned out, so that it can be soaked in a certain chemical to dissolve it, what is the way?

Molybdenum is stable in air at room temperature and produces trioxide at 500 C and oxygen. Molybdenum trioxide is slightly soluble in hydrochloric acid, easily soluble in hot concentrated sulfuric acid and nitric acid, and can be dissolved in ammonia and alkali solution, so it is dissolved in dilute sodium hydroxide solution to wash away.

We have been focused on developing, producing and marketing tungsten and molybdenum since 1994 and owned good reputation. Please be free to get the factory supply products from our company.
