Fine Blue Tungsten Oxide 199

Fine blue tungsten oxide is a blue powder with the grain size of 7~12μm. Basic Measurement Principle of Oxygen Index in Blue Tungsten Oxide The oxygen index is used to characterize the change of the number of oxygen atoms in blue tungsten oxide (BTO), that is, to reflect whether the content of tungsten contained in BTO powder is high or low. The larger the value, the lower the content of tungsten in blue tungsten oxide, and vice versa. The determination…
