Claims20
A manufacturing method for a refractory filler, comprising:
- melting a raw material batch;
- and
- cooling the melt to precipitate willemite as a main crystal phase.
A refractory filler having willemite precipitated therein as a main crystal, which is produced by melting a raw material batch and cooling the resultant melt.
A refractory filler having willemite precipitated therein as a main crystal,
- the refractory filler comprising, as a composition in terms of mol %, 50 to 80% of ZnO, 10 to 40% of SiO2, and 0.1 to 10% of Al2O3,
- wherein the refractory filler has a ratio of the willemite to an Al-based crystal of 100:0 to 99:1 in terms of molar ratio.
