The commercial grades are commonly modified with Mn(II) and Mn(III) oxides. These pigments are slightly more heat stable than the copper blacks, but not as heat stable as the cobalt blacks. They have a slight brown undertone compared to the... 

When blacks of greater heat stability than copper blacks are needed, cobalt blacks must be used. Cobalt blacks have the general formula (Co, FeiJM204, for x = 0 to 1, M = Fe, or Cr and Fe, and are described as C.I. Pigments Black 29 and Black 27, respectively. Nickel(II) oxide is the most commonly employed modifier. Because they contain a significant amount of cobalt, they are significantly more...
