| Abstract: | The solubility of Nb(OH)5 in the solution with certain HF concentration was determined. The neutralization deposition process of high-purity H2NbOF5 was studied. The influence of some factors, such as ammonia liquid neutralization, free ammonia neutralization, ammonia liquid flow rate and free ammonia pressure, on the crystallization dynamics and the subsequent products, Nb2O5 powder size characteristics was researched. |
