| | POTASSIUM STANNATE TRIHYDRATE Usage And Synthesis |
| Chemical Properties | White to light-tan crystals. Sol-
uble in water; insoluble in alcohol. | | Uses | Potassium Stannate Trihydrate can be use for composite for ion batteries. | | Uses | Textiles (dyeing and printing), alkaline tin-
plating bath. | | Hazard | Highly toxic. | | reaction suitability | reagent type: catalyst
core: tin | | Safety Profile | Poison by intravenous
route. When heated to decomposition it
emits toxic fumes of Sn. | | Synthesis | Preparation of potassium stannate solution: mounting the pretreated ion exchange membrane into an isolated electrolytic tank, injecting potassium hydroxide solution into both a cathode area and an anode area, wherein the anode is set to be 10mm in thicknessA 40mm metal tin plate, a cathode is a stainless steel plate with the thickness of 5mm, and the current density is 1-3A/dm at the temperature of 50-80 DEG C2. The diaphragm electrode is carried out under the condition, when the concentration of tin ions in the anode area is 5-10%, the electrolysis is stopped, the solution in the anode area is taken out, and the potassium stannate solution is obtained after filtration. |
