The invention provides spinel type superfine green nano-ceramic pigment and a preparation method thereof. The method comprises the following steps: 1) a Co salt and a Ti source are dissolved in distilled water and stirred properly with a glass rod until complete dissolution; 2) a stabilizer is added; 3) pH is regulated to 5.0-7.0; 4) a certain quantity of a crosslinking agent is added to the mixedsolution, and a gelatinous solution is formed; 5) in terms of Co and Ti for the Co salt and the Ti source, the mass ratio of the stabilizer, the crosslinking agent, Ti and Co is (3.95-4.05):(0.95-1.05):(0.95-1.05):(1.95-2.05); 6) the gelatinous solution is evaporated; 7) heat treatment and grinding are performed, and green TiCo2O4 ceramic pigment as a product is obtained. The ceramic pigment hasthe advantages of small particle size, good dispersity, bright color, good stability and high infrared reflectivity. 种尖晶石型超细绿色纳米陶瓷颜料及其制备方法，包括如下步骤：1）将钴盐和钛源溶解在蒸馏水中，并用玻璃棒适当搅拌，待其完全溶解；2）加入稳定剂；3）调节pH至5.0-7.0；4)将定量的交联剂加入混合溶液中形成凝胶状溶液；
