ABO3 type transition metal oxide composite rare earth tantalate ceramic/coating with infrared radiation shielding and high emissivity and preparation method of ABO3 type transition metal oxide composite rare earth tantalate ceramic/coating
The invention discloses ABO3 type transition metal oxide composite rare earth tantalate ceramic/coating with infrared radiation shielding and high emissivity and a preparation method thereof, and belongs to the technical field of thermal barrier coating materials. The ABO3 type transition metal oxide composite rare earth tantalate ceramic/coating with infrared radiation shielding and high emissivity prepared by the invention is characterized in that ABO3 type transition metal oxide with intrinsic high absorption characteristics is dispersed and distributed in a rare earth tantalate ceramic base phase. The ABO3 type transition metal oxide composite tantalate ceramic with infrared radiation shielding and high emissivity and the coating prepared by the invention have ultra-low infrared transmittance (T is less than or equal to 0.2%) in a wavelength range of 400-2500nm, and have excellent infrared radiation shielding characteristic; the average emissivity gt of the infrared band (2.5-14 [mu] m); 0.9, 0.9; the heat conductivity upwarp trend at the high temperature (greater than or equal to 800 DEG C) is obviously inhibited, and the method has very important significance.
