Abstract
A transparent, polycrystalline ceramic is described. The ceramic comprises crystallites of the formula ACBDEF, whereby A and C are selected from the group consisting of Li, Na, Be, Mg, Ca, Sr, Ba, Al, Ga, In, C, Si, Ge, Sn, Sc, Ti, Zn, Zr, Mo, Ru, Pd, Ag, Cd, Hf, W, Re, Os, Ir, Pt, Hgand mixtures thereof, B and D are selected from the group consisting of Li, Na, K, Mg, Al, Ga, In, Si, Ge, Sn, Sc, Ti, Zn, Y, Zr, Nb, Ru, Rh, La, Lu, Gdand mixtures thereof, E and F are selected mainly from the group consisting of the divalent anions of S, Se and O and mixtures thereof, x, u, y, v, z and w satisfy the following formulae0.125<()/()≦0.55=4and at least 95% by weight of the crystallites display symmetric, cubic crystal structures of the spinel type, with the proviso that when A=C=Mgand B=D=Al, E and F cannot both be O.
