niobium pentoxide powder for optical glass
Product Description
Niobium pentoxide powder is an important chemical raw material. It is also a black powder with a high melting point and stable chemical properties, which is generated by the reaction of the metal niobium with oxygen at high temperatures. Niobium pentoxide powder has stable chemical properties, insoluble in water, acids and bases, and only reacts with hydrogen and carbon at high temperatures. Niobium pentoxide powder is widely used in electronics, ceramics, optics, chemistry and other fields. In the field of electronics, it is used as a cathode material for electron guns, and in the field of ceramics, it is used as an additive for ceramic materials to improve the hardness and heat resistance of ceramics. In addition, niobium pentoxide powder can also be used in the manufacture of optical devices and chemical catalysts.

Application
Quality control system
Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.
Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
