초록
아연결정유약은 결정생성의 요건을 맞추기 위해서는 조핵제의 생성 - 조핵제의 양 조절 - 결정의 성장 등의 까다로운 소성과정을 거쳐야 한다. 소성온도 폭이 좁고 아연의 상태에 따라 결정에 영향을 미치는 등 사용이 용이하지 않다. 아연결정생성을 촉진시켜 이를 Frit화하여 폭넓은 소성조건에서 안정적으로 재결정화도록 하여 상용유약으로 유약을 개발할 수 있다.
Abstract
Crystallization of zinc crystalline glaze requires demanding conditions such as the formation of a nucleating agentand the amount of nucleating agent, and growth of crystalline. Zinc crystalline glaze is hard to utilize in the industry becauseof its narrow range of the firing temperature, and the crystallization’s dependency on the quality of zinc. Stimulation ofzinc crystallization and formation of frit enable zinc crystalline glaze to be reconstituted in a various range of firingschedules, leading to the development of a competitive industrial glaze.
