Preparation of a suspension in preparation of powder making |
摘要 |
A highly concentrated silver salt suspension and tin salt suspension from which a silver and tin oxide powder can be made under utilization of the reaction spray method is made by adding in small steps a tin II salt solution into a small volume of concentrated nitric acid while maintaining a temperature below 40 degrees C. to obtain an injection suspension of a tin II salt solution, the injection suspension is then mixed with about a three fold quantity (volume) of concentrated 65% nitric acid, the latter mixture is then added in small steps to a watery citrate solution and combined with tin granules until all tin granules are dissolved and changed into a tin IV oxide hydrate suspension; the completed tin IV oxide hydrate suspension as per the preceding step is mixed with a watery silver nitrate solution.
