Method for preparing infrared radiation ceramic material

A method for preparing an infrared radiation ceramic material, comprising:

• mixing and ball milling raw materials of Fe2O3, MnO2 and CuO in a mass ratio of x:(9-y):y to obtain a mixed powder, where 0<x<9, and 0<y<9;
• pressing the mixed powder;
• irradiating or sintering by a first laser with a first irradiating parameter the pressed mixed powder in a first crucible for a solid-phase reaction to obtain an AB2O4 type ferrite powder;
• obtaining a first mixture by mixing the AB2O4 type ferrite powder and a cordierite powder in a mass ratio of m:(100-m), where 0<m<100, and adding 0 to 5% of each of a sintering aid and a nucleating agent based on a total mass percent of the raw materials material for ball milling;
• obtaining a second mixture by mixing the first mixture with 1% to 5% of a binder based on the total mass percent of the raw materials and aging for 10 h or more;
• pressing the second mixture;
• and irradiating or sintering by a second laser with a second irradiating parameter the pressed second mixture in a second copper crucible for a solid-phase reaction to obtain the infrared radiation ceramic material, wherein each of the first irradiating parameter and the second irradiating parameter comprises at least one of laser spot, laser power and laser sintering time.
