Application Of Glass Powder Zinc Oxide (Indirect Method) :
1, In the different types of glass to add ingredients zinc oxide, the glass can have a special character.
Such as photosensitive photosensitive glass and ceramics used in place of 5% zinc oxide of silica,we can significantly reduce the thermal expansion coefficient, increased light sensitivity and optical density of nearly 20 times.
In the optical glass composition by adding zinc oxide to make glass with high refractive index, UV absorption and light transmission performance. Electric glass zinc oxide to give a series of electrical and semiconductor properties, so that could be used to print circuits,capacitors, resistors, and conductive products.
2, zinc oxide in the crafts or food containers of transparent glaze and coarse rough translucent ceramic glaze has been applied earlier.
