ABSORBENT THERMOSTABILISING MATERIAL BASED ON MANGANITES OF RARE-EARTH ELEMENTS, PREPARATION METHOD AND THERMOSTABILISING COATING BASED ON SAID MATERIAL Russian patent published in 2010 - IPC C01G45/12 C01F17/00 

FIELD: chemistry.

SUBSTANCE: absorbent thermostabilising material based on manganites of rare-earth elements is obtained in fine powder state. Manganites having phase transition dependency of radiation capacity on temperature and general formula A_(1-X)B_xMnO₃ are used, where A is a rare-earth element, B is a substituting element, x ranges from 0.1 to 0.3. Compounds of corresponding elements are selected. Their concentration is selected to create the required composition. The compounds are mixed and heated until formation of a solid solution which is ground. Binder and solvent are added to the obtained material in the require proportion. The obtained mixture is stirred until obtaining a homogeneous mass and the applied onto the surface to be coated in a thin layer.

EFFECT: obtaining the desired product with high output.
