Regarding the issue of controlling the size of precipitated particles
Thread Content
Ce3+ first reacts with ammonia water to form Ce(OH)3 precipitate; thereafter, the addition of hydrogen peroxide and heating lead to the formation of Ce(OH)4 precipitate. It is required that the D50 value of Ce(OH)4 be less than 3 μm, but in our experiments the D50 value is around 20 μm. What reactions or conditions can be used to control and reduce the particle size of the resulting product?
Is it possible to control the feed rate of the raw materials and make it as slow as possible?
