Abstract
The invention relates to novel transparent glasses, vitroceramics, and transparent or translucent ceramics containing, in relation to the total composition of the glass, vitroceramic, or ceramic, at least 60 wt % of a composition having the following formula (I): (M1O)x(M2O)y(M3)2O3)z(Al2O3)100−x−y−z (I), where M1 is an element selected from among Ba and/or Sr, M2 is an element selected from among Mg or Ca, x and y are numbers such that 30≦x+y≦80, y is between 0% and 10% of x, M3 is an element selected from among B, Ga, or In, and z is a number between 0% and 10% of (100−x−y). The invention also relates to the method for manufacturing said compositions and to the uses of said compositions in the field of optics.
