[PDF] Controlling the formation of Na2ZrSiO5 in alkali ...
In the alkali fusion process for the production of zirconium oxychloride, the formation of the water insoluble byproduct, Na2ZrSiO5, largely affects NaOH recovery and results in the formation of silicon slags. Thus, controlling Na2ZrSiO5 formation is necessary. In this paper, we studied the effects of roasting temperature, NaOH/zircon mole ratio, and particle size of .
