β型四钼酸铵的制备及结晶过程
The preparation of ammonium β-tetramolybdate
and the crystallization process
摘要
Abstract
The ammonium β-tetramolybdate was prepared and the preparing process included two courses: preparing ammonium tetramolybdate by the method of acidified deposition; and preparing ammonium β-tetramolybdate by the method of seeded decomposition. The second course included two processes: one was born of crystal seeds(pH=1.2), the other was growth of crystal seeds(pH=2~3). The TGA and DTA proved that the crystal was ammonium α-tetramolybdate prepared by the method of acidified deposition and was ammonium β- tetramolybdate prepared by the method of seeded decomposition. The thermodynamics and the dynamics of the process were analyzed. The mechanism of crystallization process and the control of the crystalline were discussed simply in this paper.关键词
