Cobalt blacks

Unsupported, or bulk cobalt catalysts are commonly used as model systems to avoid the influence of support interactions. Bulk cobalt (also known as cobalt black) is typically produced by reduction of Co304, leading to a porous solid with a low...

Reactor testing setup The catalyst was tested in a down-flow 3/8" OD stainless steel tubular fixed bed reactor. The charge consisted of 6.8 g of the C03O4 catalyst diluted with 18 g of quartz powder. Reduction of C03O4 should then result in a 5 g yield of cobalt black. To even out the temperature profile, in...

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...
