A kind of preparation method of indium oxide spherical powder with controllable particle shape |
| abstract |
A method for preparing spherical indium oxide powder with controllable particle shape, comprising the steps of: (1) reacting a sulfuric acid solution with a concentration of 35-50% with metal indium, the reaction is carried out for a certain time, and then adding a concentration of 65-68% % nitric acid solution reacts with metal indium to obtain a mixed solution system containing indium sulfate and indium nitrate; (2) adjust the concentration of indium ions in the mixed solution system between 0.45 and 0.6M; (3) mix the mixed solution with a precipitant Carry out a precipitation reaction until the pH of the solution is between 9 and 10, and then precipitate and age the solution for a certain period of time to obtain an indium hydroxide precursor slurry; (4) filter and wash the precursor slurry with a ceramic membrane until the pH of the washing filtrate is reached When the value is between 7 and 8, and the conductivity is less than or equal to 50 μS/cm, the washing is completed, and the purified precursor sample is obtained; (5) the precursor sample is dried at 80-130 ℃; (6) the precursor test The sample is ball-milled, and then the precursor is calcined at the calcination temperature to obtain indium oxide powder. |
