說明:白色粉末,不溶于水,可溶于酸。極易吸潮,能迅速吸收空氣中的水份和二氧化碳,應置于密封容器內。 | Description: White powder, insoluble in water, soluble in acids, As it is highly hygroscopic and absorb the moisture and carbon dioxide from air rapidly, it should be kept in sealed containers. Uses: Used as the raw material of the industries of glass, ceramics and electronics. |
