Abstract

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