Abstract

본 발명은 인공치아의 치관용 도재의 제조방법에 관한 것으로서, 질산알루미늄 9수화물 1몰 , 구연산칼륨 1수화물 1몰, 콜로이드규산 4몰을 각각 물과 혼합하여 졸로 제조하고 이들을 혼합한 다음 겔화 촉진제를 첨가하여 겔화시키고, 건조, 하소, 분쇄, 열처리하여 제조한 백류석 5∼30중량%와 일반적이 저용융 글라스분말70∼95중량%를 혼합 소결하여 도재를 제조하는 방법으로 본 발명의 도재는 열팽창계수가 높아서 인공치아의 금속코어에 도포, 소성하였을 경우 균열이 생기지 않고 기계적, 화학적 특성이 우수하다.The present invention relates to a method for producing a ceramic porcelain ceramic tooth, 1 mole of aluminum nitrate hexahydrate, 1 mole of potassium citrate monohydrate, 4 moles of colloidal silicate is mixed with water to prepare a sol and then mixed with a gelation accelerator The porcelain of the present invention is thermally expanded by mixing and sintering 5-30% by weight of calcite prepared by drying, calcining, pulverizing and heat-treating and generally 70-95% by weight of low-melting glass powder. When the coefficient is high, it is excellent in mechanical and chemical properties without cracking when applied to the metal core of artificial teeth.
