Pigments based on lisbo3 and linbo3 related structures

Abstract

The present invention involves pigments derived from compounds with the LiSbO-type or LiNbO-type structures. These compounds possess the following formulations MMZ, MMMMZ, MMMZ, MMMMZ, MMMZ, MMMZ, or a combination thereof. The cation Mrepresents an element with a valence of +1 or a mixture thereof, the cation Mrepresents an element with a valence of +2 or a mixture thereof, the cation Mrepresents an element with a valence of +3 or a mixture thereof, the cation Mrepresents an element with a valence of +4 or a mixture thereof, the cation Mrepresents an element with a valence of +5 or a mixture thereof, and the cation Mrepresents an element with a valence of +6 or a mixture thereof. The cation M is selected from H, Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Ru, Co, Ni, Cu, Ag, Zn, B, Al, Ga, In, Si, Ge, Sn, P, Sb, or Te. The anion Z is selected from N, O, S, Se, Cl, F, hydroxide ion or a mixture thereof. Along with the elements mentioned above vacancies may also reside on the M or Z sites of the above formulations such that the structural type is retained. The above formula may also include M dopant additions below 20 atomic %, where the dopant is selected from H, Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Ru, Co, Ni, Cu, Ag, Zn, B, Al, Ga, In, Si, Ge, Sn, P, Sb, Bi, Te, or mixtures thereof.
