CERAMICS
The properties imparted by Zinc Oxide to some of the newer
applications are as electronic glass, low-melting glass for
metal-to-glass seals, thermistors for use as lighting
arresters and devitrified glasses of low thermal expansion.
Zinc Oxide imparts a unique combination of properties when
used in glass. Zinc Oxide reduces the coefficient of thermal
expansion, imparts high brilliance and luster and high
stability against deformation under stress. As a replacement
flux for the more soluble constituents, it provides a
viscosity curve of lower slope. The specific heat is decreased
and the conductivity increased by the substitution of Zinc
Oxide for BaO and Pbo.
PHARMACEUTICAL INDUSTRY
Zinc Oxide is mainly used in Zinc soap, ointment, dental
inlays, food powders etc. Zinc Oxide forms an indispensable
element of the production process of this industry. |
