查询词典 oxide thorium

The results show that the increasing weight of tungsten oxide nanopowders and the color of tungsten nanomaterials turns light yellow from dark blue and black by increasing oxygen partial pressure in blown gas; the decreasing weight of tungsten oxide nanopowders and the color of tungsten oxide nanopowders becomes dark blue by the plasma that compares row increase including the hydrogen.The tungsten oxide nanomrods was increasing with chamber pressures. Urged nanoparticles to have the clavate fusion phenomenon in the development process with increasing plasma currents, and increased the nanorods distribution quantity along with the generated time to be more, 12 minutes later presents all nanorods. This system to prepare a monoclinic crystal W18O49 nanorods successfully, each hourly output approximately is 0.33 gram, and monoclinic crystal WO3 tungsten oxide nanoparticles, each hourly output approximately is 5.77 grams, its growth mechanism is Vapor-Solid solidly the physiognomy explanation.

A method for the analysis of zinc oxide phase content in sulfide ore was studied. On the basis of the characteristics of each phase component, the sulfide ore sample was leached twice with NaOH and acetic acid-ascorbic acid, respectively, so that the oxide mineral and zinc oxide were dissolved completely. The leaching rate of zinc oxide phase was up to 98 Vo. Moreover, the dissolution of zinc sulfide phase was effectively inhibited, solving the problems of selective leaching and determination for zinc oxide.
