Abstract
Dissolution of ZrO2 oxide in synthetic CaO - Al2O3 - SiO2 -
Na2O - B2O3 mould fluxes was investigated in situ using a
Confocal Scanning Laser Microscope (CSLM). Evolution of
particle radius with time is obtained exhibiting strong dependence
on temperature and basicity of the mould fluxes. The
rate-limiting step of the dissolution process was discussed, and
basicity was shown to significantly influence the rate-limiting step.
