How gray is produced?

Antimony tin gray is solid soluble in SnO2, so it is gray.Sb2O4 is produced by heating Sb2O3 in the compound material during the preparation of the color material.that means Sb3+Sb5+O4 is a composite oxide, among which the coordination number of Sb3+ and Sb5+ is 6.Sb3+ in Sb2O4 replaces Sn4+ in SnO2 to form a substitutional solid solution.Its replacement equation is: Sb3+ + Sb5+ ⇋2Sn4+.It's a beautiful blue-gray color.If the vanadium is dissolved in a solid solution, SnO2[Sb,V] is grayish in color.In addition, Zr-Si-Co-Ni zirconium lime is also present in the system.
