生产制备方法及用途展开↓

制备方法

1.偏锡酸与氢氧化钾中和，生成锡酸钾溶液，经沉淀、蒸发、结晶制得产品。2.工业上制造锡酸钾的方法是将锡花、苛性钾、硝酸钾和水加入反应釜中，加热使物料开始反应后立即停止加热，其反应热使温度持续升高，直至温度恒定。然后继续加热并充分搅拌，物料升温至规定温度，停止加热，然而搅拌尚需进行，经过约半小时，慢慢冷却出料，即得粗锡酸钾，其反应如下：将粗锡酸钾用水溶解后，加适量硫化钠除铅并加热至沸，取澄清的净化液移入除铁槽，加入过氧化氢除铁，沉淀过滤后，经浓缩、结晶、离心脱水、干燥、粉碎，即得成品锡酸钾。

用途简介

锡酸钾在电镀工业主要用于以锡代银、以锡铜合金镀层取代镍镀层。它不仅可降低生产成本,同时以钾代替钠能产生较高的阴极效率及电导率,提高镀件表面光亮度、附着力和抗腐性,如用在汽车制造、电子行业、罐装食品盒、人民币等的电镀。锡酸钾还可在印染工业中作媒染剂、纺织工业作增重剂等。此外,在玻璃陶瓷工业、高级装饰材料中也有广泛的用途。

物化性质展开↓

外观与性状：
白色至灰白色粉末
密度：
3,197 g/cm3
熔点：
140°C (dec.)
稳定性相关：

在潮湿空气中易吸收空气中的二氧化碳而分解，并生成碳酸钠和氢氧化锡，从而导致它难溶于水。锡酸钾在水中的溶解度在15℃时为110.5g/100g水，而且其溶解度随温度的升高而增加。然而它在水中的溶解度又随着相应的游离碱的增加而减少。锡酸钾加热到140℃失去三个结晶水而成为无水物　锡酸钾在水溶液中的水解产物为水合锡氧化物。为了增加锡酸钾的化学稳定性，在市售商品锡酸钾中通常含适量的游离碱———苛性钾，因此商品的锡酸钾化合物含锡小于纯化合物39.7%的理论值.

其它信息：

1.性状：白色或淡棕色结晶粉末

2.溶解性：易溶于水，呈碱性，不溶于醇和丙酮。
