Green pigment

A method for producing a green pigment, said method comprising the steps of:

• producing a mixture by mixing carbonates, nitrates, oxalates, phosphates, hydroxides, fluorides, borates, or corresponding metal organic compounds of metals selected from Co, Zn, Ca, Mg, Cu, Li, Na, Ti, Mn, Sn, Ge, Cr, B, Fe, Mn, Al, Ni and Nb;
• and
• calcining the mixture at a temperature from 900° C. to 1400° C. for 1 h to 3 h to form a pigment of a formula selected from the following formulas
• a) (A1−xB1+x)(C3−x−yD2xB1−x−2yNi3y)O8, wherein 0.05≤x≤0.9 and 0.05≤y≤0.5, and wherein x+2y≤1;
• b) (A1−xB1+x)(C3−x−yD2x−yB1−x−yNi2y)O8, wherein 0.05≤x≤0.5 and 0.05≤y≤0.5;
• c) (A1−xB1+x)(C3−x−4yD2xB1−x+yNby)O8, wherein 0.05≤x≤0.5 and 0.05≤y≤0.2;
• d) (A1−xB1+x)(C3−xD2x−2yB1−x+yNby)O8, wherein 0.05≤x≤0.9 and 0.05≤y≤0.2, and wherein x≥y;
• and
• e) (A1−xB1+x)(C3−x−3yD2xB1−xNb2yNiy)O8, wherein 0.05≤x≤0.9 and 0.05≤y≤0.2,
• wherein in said formulas A is at least one element selected from Co, Zn, Ca, Mg and Cu, B is at least one element selected from Li and Na, C is at least one element selected from Ti, Mn, Sn and Ge, and D is at least one element selected from Cr, B, Fe, Mn and Al.
