Claims9
A manufacturing method for refractory filler particles, comprising:
- preparing a raw material batch so that the refractory filler particles comprise, as a composition in terms of mol %, 50 to 80% of ZnO, 10 to 40% of SiO2, and 0 to 10% of Al2O3;
- melting the raw material batch to obtain a melt;
- and
- cooling the melt to precipitate willemite as a main crystal phase to obtain the refractory filler particles.
