The C@ZrSiO 4 pigments offer a viable alternative to spinel black pigments, but they have poor tinting strength due to low encapsulation rate. The aggregate and irregular morphology limits their application. Herein, as a three‐in‐one solution for the above issues, we report a highly dispersed submicronic inclusion black pigment with deep dark hue by double‐shell reaction sintering method for the first time. The morphological advantage of spherical CSs (carbon spheres) @ZrSiO 4 pigments has successfully stimulated a significant increase in chromatic performance with L * value of 13.58. In addition, the suspension stability of the pigments in solution was verified, and the effect of the order of double shell on the encapsulation efficiency was studied.
