氯化锶制备
1.盐酸法
先将天青石粉碎至200目，加入反应器中与水搅拌，然后缓慢地加入工业盐酸，通入蒸汽搅拌，除去钙盐等杂质。然后倾析并洗涤至中性。将洗涤后之料浆，用水搅拌，再加入纯碱，通人蒸汽加热进行反应，生成碳酸锶，用水洗涤至中性，洗去硫酸钠和未反应的纯碱，再加入盐酸进行酸解反应，反应终点控制溶液pH 4～5。在加热近沸腾情况下，加入10％稀硫酸和30％过氧化氢，除去可溶性钡盐和铁。过滤澄清后的溶液，经蒸发浓缩至42～43°Bé后冷却结晶，离心分离，在220～250℃干燥，制得无水氯化锶。其反应方程式如下：
2.首先将浓盐酸34mL加入20mL水制得稀盐酸溶液，在搅拌下将30g(约0.2mol)碳酸锶分批加入，这时就会放出CO2并得到氯化锶溶液，过滤除去不溶物。滤液在水浴上浓缩，放置片刻便析出结晶。用吸滤法过滤，少量水洗结晶，然后将结晶夹在滤纸间自然干燥，收率约57%。如将母液再浓缩，尚可得少量结晶，产品为六水合氯化锶。加热至61.5℃生成二水合物（板状结晶）。加热100℃生成无水氯化锶。
