Abstract

"CERAMICA DE VIDRO OPALESCENTE". A presente invenção refere-se a uma cerâmica de vidro opalescente, especialmente uma cerâmica de vidro opalescente como material dental ou como aditivo ou como componente de material dental, abrangendo pelo menos os componentes SiO~ 2~, Al~ 2~O~ 3~, P~ 2~O~ 5~, Na~ 2~O, K~ 2~O, CaO bem como Me(IV)0~ 2~. Para obter uma opalescência aperfeiçoada com transparência simultaneamente melhor bem como uma temperatura de combustão ajustada para outros materiais e dilatação térmica bem como fluorescência, está previsto, que a cerâmica opalescente é isenta de ZrO~ 2~ e TiO~ 2~ ou é essencialmente isenta de ZrO~ 2~ e de TiO~ 2~, que a cerâmica de vidro apresenta um teor de Me(II)O de menos do que aproximadamente 4% em peso e que o teor de Me(IV)O~ 2~ importa em aproximadamente 0,5 até 3% em peso. Além disso, é proposto um processo para a preparação da cerâmica de vidro opalescente. A cerâmica de vidro pode ser aplicada como material dental ou como aditivo ou como componente de material dental.
