| 储存条件 | 室温，干燥 |
| 稳定性 | 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. |

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。
