scope note
| - An infusible, insoluble white solid oxide of zinc (ZnO) in the form of a fine white powder used in compounding rubber, as a fungicide, as an absorber of ultraviolet radiation, in pharmaceuticals, in cosmetic preparations, in pigments, as a component in paint to toughen and prevent yellowing, as a semi-conductor, in photocopying processes (related to its photoconductivity), and in ceramic glazes, printing inks, glass colorants, enamels, and lubricants. Zinc oxide is prepared in either of two ways: by the oxidation of pure zinc or by roasting zinc ore. Zinc oxide has been used for various purposes since the Middle Ages, but was rarely used in making pigments until the 19th century. (en)
- 一種不可熔也不可溶的白色固體氧化鋅(化學式為ZnO),其形態為細粒白色粉末,可用於合成橡膠,可當作殺真菌劑,可用於吸收紫外線輻射,可製造藥品,可調製化妝品,可用於顏料,可當作油漆成分來強化性能及防止其變黃,可做為半導體,可用於複印過程(因其具光導性),可製造陶瓷釉、印刷墨、玻璃著色劑、琺瑯和潤滑劑。氧化鋅有兩種製造方法:由純鋅氧化或烘燒鋅礦石而成。氧化鋅自中世紀即具多種用途,但直至十九世紀才被用來製造顏料。 (zh-hant)
