STANNOUS FLUOBORATE - Nature
Open Data Verified Data
colorless or transparent liquid. Relative density (20 degrees C) 1.65. When the aqueous solution contains a certain free acid, it is acidic, and the pure product is slightly alkaline. Heat or water decomposition or hydrolysis. Long-term exposure to air is susceptible to oxidation.

STANNOUS FLUOBORATE - Preparation Method
Open Data Verified Data
metal tin fluoroboric acid method: first cut the tin ingot into small pieces, heat it on the electric furnace to melt it, then pour it into cold water to form tin flowers, remove it and pour it into the reactor, then add fluoroboric acid, the compressed air was bubbled to fully react. The reaction solution was filtered to remove impurities, and a stannous fluoroborate product was obtained.

| Application | used for high-speed tin plating of copper wire, preparation of tin or tin alloy electroplating solution, etc. for electroplating. electroplating industry |
| production method | 1. Metal tin fluoroboric acid method first cut the tin ingot into small pieces, heat it on the electric furnace to melt, and then pour it into cold water to form tin flowers, remove it into the reactor, then add fluoroboric acid, the compressed air was bubbled to fully react. The reaction solution was filtered to remove impurities, and a stannous fluoroborate product was obtained. The reaction equation is as follows: 2. The chemical method first places the prepared fluoroboronic acid in a reactor, and then slowly adds stannous oxide under stirring. After the reaction is complete, insoluble impurities are removed by filtration to obtain a finished stannous fluoroboronary product. The reaction formula is as follows: |
