<p>The present invention relates to the use of alumina particles in the composition subjected to a fritting operation for manufacturing a ceramic product, so as to obtain an opacifying effect in said ceramic product. Said use is characterized in that the alumina particles used have less than 96 wt % alpha-alumina and a specific surface, measured with nitrogen using the Brunauer-Emmett-Teller (BET) technique, no lower than 1 m2/g.</p> |
