Introduction to knowledge in high purity molybdenum trioxide

High-purity molybdenum oxide MoO 3 weight percent is generally from 99.8% to 99.99% base material which is prepared to take the metal molybdenum powder, as starting material may be of high purity reagents. The basic raw material for the production of high-purity molybdenum trioxide is molybdenum calcine - industrial molybdenum trioxide powder.
The production of high-purity molybdenum trioxide powder from molybdenum calcine has two very different process routes: one is customarily called wet method - from the calcination by ammonia leaching, the wet method to purify, to produce ammonium paramolybdate powder, Ammonium molybdate is dissociated by heating to drive away ammonia to obtain high-purity molybdenum trioxide; another customary method of fire is directly heated by molybdenum calcination, and impurities in molybdenum calcine remain in the roasting slag, and most of the three The molybdenum oxide is sublimed and recrystallized to purify to form high-purity molybdenum trioxide powder.
Both the fire method and the wet method can produce products with high purity. The common standards are shown in the table below.
