锶是一种稀有金属锶的化合物在工业上有很多用途,硝酸锶和过氧化锶是制造曳光弹、紅色信号、烟火及火箭的某些信号装置的原料。碳酸锶是平爐炼鋼的去硫剂,是制糖工业中所需的一种附加料。在制造橡胶的过程中需要硫酸锶作填充料。冶炼金属锌也要用碳酸锶或硫酸锶来提高电解鋅的純度。此外各种锶盐还可用来制造染料、漆料、除毛剂及医
Tantalum is a rare metal antimony compound that has many industrial uses. Niobium nitrate and antimony peroxide are the raw materials for certain signal devices for the manufacture of tracer bullets, red signals, pyrotechnics, and rockets. Barium carbonate is a desulfurizer for open hearth steelmaking and is an additive required in the sugar industry. Strontium sulphate is required as filler in the manufacture of rubber. Smelting metal zinc also uses barium carbonate or barium sulfate to increase the purity of electrolytic zinc. In addition, various lanthanum salts can also be used to make dyes, paints, hair removers and medical supplies.
