YAO RUNZHAN

The invention discloses porous zirconium silicate powder. The apparent porosity of the zirconium silicate powder is 5-80%, and the central particle size value D50 of the zirconium silicate powder is 1-1000 [mu]m. According to the zirconium silicate powder disclosed by the invention, the apparent porosity and the central particle size value of the obtained zirconium silicate powder are in the specific range by adjusting and controlling the raw materials and the process in the preparation method, so that the particle density and the heat conductivity of the porous zirconium silicate powder are effectively controlled. The purpose of remarkably reducing the particle density and the heat conductivity of the porous zirconium silicate powder is achieved, and the porous zirconium silicate powder has the advantages of being light in weight (small in particle density), low in heat conductivity, high in use temperature and high in infrared reflectivity. Meanwhile, the invention further discloses a preparation method of the porous zirconium silicate powder with the advantages of light weight (small particle density), low thermal conductivity, high use temperature and high infrared reflectivity, and the method is simple in process, low in cost and easy to popularize on a large scale.
