Purple Tungsten Oxide History

Purple tungsten oxide (Violet Tungsten Oxide, VTO), referred to as purple tungsten. Purple tungsten oxide refers to paratungstate (Ammonium Paratungstate, APT) as raw material was calcined under certain conditions, decomposition, reduction generated purple tungsten oxide. General purple or blue-purple crystalline powder. By strong fissile octahedral structure, intrinsic crystalline needle and rod. Purple Tungsten is a tungsten oxide, the chemical formula for WO2.72 or W18O49. Purple and yellow tungsten oxide, tungsten (the yellow tungsten WO3), blue tungsten oxide (referred to as blue tungsten W20O58 or WO2.90) and brown tungsten oxide (WO2) collectively known as tungsten oxide. The tungsten oxide can be used as raw material for the production of tungsten powder, tungsten because of its unique nature purple to purple tungsten tungsten powder products as raw materials, has generated fast, fine-grained and so on.

Purple tungsten oxide is a tungsten oxide. Purple tungsten oxide history can be traced back to produce tungsten oxide. Tungsten has a long history, dating back to the 18th century. It was first discovered by Peter Woulfe. Tungsten first to be called wolfram, element symbols for W. Swedish chemist Carl Wilhelm Scheele discovered scheelite, and its been a lot of research. In 1841, chemist Robert Oxland developed a production of tungsten trioxide and the first step of sodium tungstate. He was awarded a patent. Soon after, he is considered the founder of tungsten chemical systems.
