Abstract

Patente de Invenção:<B>"LIGAçãO DE BAIXA TEMPERATURA PARA FERRAMENTAS ABRASIVAS"<D>. A presente invenção provê uma ferramenta abrasiva ligada vítrea em que a porção de grão abrasivo compreende um grão abrasivo termicamente sensível, tal como grão superabrasivo ou grão abrasivo de alfa alumina microcristalino de sol gel sinterizado, e em que a ligação vitrificada pode ser amadurecida por aquecimento em uma temperatura abaixo de 875°C. A invenção ulteriormente inclui uma nova composição de ligação vitrificada.
