Abstract

본 발명은 통상의 방법으로 제조된 치과용 도재분말에 틱소트로피특성을 나타내는 황산 알루미늄, 황산 마그네슘, 황산 칼슘, 염화 암모늄, 염화칼슘, 수산화 칼슘 및 염산으로 이루어진 그룹으로 부터 선택된 적어도 하나의 응집제를 0.01 내지 0.25중량%, 바람직하기로는 0.04 내지 0.08중량%를 첨가하여서 된 작업성이 개선된 치과용 도재분말인 것이다.The present invention is 0.01 to at least one flocculant selected from the group consisting of aluminum sulfate, magnesium sulfate, calcium sulfate, ammonium chloride, calcium chloride, calcium hydroxide and hydrochloric acid exhibiting thixotropic properties to the dental ceramic powder prepared by a conventional method It is a dental ceramic powder having improved workability by adding 0.25% by weight, preferably 0.04 to 0.08% by weight.

본 발명에 따른 치과용 도재분말은 슬러리 상태에서 부드럽게 뭉쳐진 상태로 존재하여 도재 축성시 흘러내리지 않게 되므로 정교한 모양의 인공치아제조가 가능하게 된다.Dental porcelain powder according to the present invention is present in the aggregated state in a slurry gently so that it does not flow during the porcelain build-up, it is possible to manufacture artificial teeth of a precise shape.
