Zinc Oxide
chemical formula: ZnO
( fine powder )
Zinc Oxide has the uncanny ability to absorb ultraviolet (UV) light, which is why it's the first choice for powerful sunscreen lotions. Aside from its ability to treat minor skin irritations and burns, it makes an amazing, rock-hard adhesive when mixed with an equal amount of Calcium Carbonate and a little Sodium Silicate to form a paste. This rapid setting adhesive is typically used to plug firework tubes. Zinc Oxide also exhibits the piezoelectric effect, generating voltage under mechanical stress. It has also recently been used to produce blue LEDs.
