Abstract

The invention discloses a normal-temperature high-radiance infrared ceramic material prepared through rapid laser self-propagating sintering and a preparation method thereof. The preparation method comprises the steps that CuO, Fe2O3, MnO2 and other transition metal oxides are adopted to be subjected to ball milling according to a certain proportion, drying, compacting and tabletting are conducted after ball milling is conducted, then the obtained product is placed in a copper crucible or on other matrixes, laser spot, power, time and other parameters are adjusted to carry out laser irradiation or sintering to enable the raw material mixture to be subjected to high-temperature solid-phase reaction, and thus the AB2O4 type ferrite material is obtained; secondly, the prepared ferrite is crushed, the crushed ferrite is mixed with cordierite according to a certain proportion, a proper amount of a pore-forming agent and a sintering aid are added, long-time ball milling, drying is carried out, and compacting and tabletting are carried out; and high-temperature sintering is carried out by using laser to finally obtain the high-radiance composite ceramic material. The method has the advantages of short sintering time, low energy consumption and the like, and the obtained composite ceramic material has high normal-temperature infrared radiance and wide application prospects.

Description

technical field [0001] The invention belongs to the field of infrared luminescent ceramic materials, in particular to a room temperature high emissivity infrared radiation ceramic material and a preparation method thereof. Background technique [0002] The use of traditional infrared emitting materials requires a heat source to provide a high temperature environment, which makes it difficult to meet the requirements for the use of infrared emitting materials in a normal temperature environment. The specific room temperature infrared radiation ceramic material has a high light-to-heat conversion efficiency at room temperature, does not need a heat source, and can absorb the heat of the surrounding environment. It has broad application prospects in the fields of daily-use ceramics and architectural ceramics. [0003] Since the 1990s, there have been more and more researches on high-temperature infrared radiation materials in my country, and some progress has been made. In 1992...
