Zinc Oxide - White Hexagonal Crystals Non-soluble In Water Uv Protection Pigment And Medical Applications

Zinc Oxide
Zinc oxide chemical compound ZnO which is nearly insoluble in
water but soluble in acids or alkalis. It occurs as white hexagonal
crystals or a white powder commonly known as zinc white. Zinc white is
used as a pigment in paints; less opaque than lithopone it remains
white when exposed to hydrogen sulfide or ultraviolet light. It is also
used as filler for rubber goods and in coatings for paper. Chinese
white is a special grade of zinc white used in artists' pigments.
Because it absorbs ultraviolet light zinc oxide can be used in
ointments creams and lotions to protect against sunburn. Crystalline
zinc oxide exhibits the piezoelectric effect is luminescent and is
light sensitive. Zinc oxide occurs in nature as the mineral zincite. It
is used in:
