1. A high emissivity coating composition, comprising
a powder mixture for providing emissivity;
a binder for providing adhesion; and
a co-binder for promoting adhesion and film-forming,
wherein
the powder mixture comprises at least three metal compounds of formula A(y−3)By/2Oy, wherein y is 4; A is selectable from a group of Ni and Co; B is selectable from a group of Fe and Cr; and O is oxygen; and
the co-binder is an aqueous solution comprising silica in a compound of Formula (1):

OG Complex Work Unit Chemistry
wherein R1 is H-Si-(CH3)2; and
silica in a compound of Formula (2):

OG Complex Work Unit Chemistry
wherein R2 is CH3.
