Yellow tungsten oxide is also called tungsten trioxide. Conventional yellow tungsten oxide products generally have two different grades of average grains that exhibit different colors. When the yellow tungsten oxide crystal size is about 1.5um, it appears yellow. When the yellow tungsten oxide crystal size is about 15um, it appears yellow-green.
Yellow tungsten oxide is generally used to produce tungsten powder, and in recent years, it has also been used to produce thermal insulation films, electronic components, photovoltaic silver pastes and raw materials for lithium battery cathodes.
