![]() Compared with the prior art, the preparation method of the near infrared high reflection chromium oxide based pigment from hydrated chromium sesquioxide provided by the invention is a clean preparation process, and the obtained product has high infrared reflectivity while maintaining the green hue of the chromium oxide pigment. The chromium oxide green pigment obtained by the invention has near infrared reflectivity above 85%, visible light area of dark green, and chroma parameters respectively of: brightness L* of 40-45, red and green value a* of -16 to -18, and yellow and blue value b* of 15-22. The additive is one or more selected from compounds containing aluminium, titanium, vanadium, manganese, iron and cobalt iron with radius of 0.040-0.080. The hydrated chromium sesquioxide can be prepared from a solid phase method (such as a chromium salt gas reductive method) or a liquid phase method (such as deposition and hydrothermal method). The hydrated chromium sesquioxide as a raw material is uniformly mixed with an additive in a certain proportion, and the mixture is calcined at 950-1300 DEG C for more than 0.5 h to obtain the chromium oxide based pigment. The invention relates to a preparation method of a near infrared high reflection chromium oxide based pigment from hydrated chromium sesquioxide.
