PROCESS FOR THE PREPARATION OF GRANULAR CERAMICS

摘要

pulverizing and distributing single taste and single phase minerals having a refractoriness of SK 25-26; fine-pulverizing said minerals; mixing finer minerals uniformly; granulating said mixed minerals by moving irregularly and dispersing an aqueous soluble salts of a transition metal to permeate and absorb into the particle; drying the granulating particles; distributing the dried particles uniformly; melting the distributed particles and firing them at high-temperature to color in a clear tone.
