CERAMIC PYROELECTRICAL MATERIAL FOR IR RADIATION RECEIVERS WITHOUT COOLING Russian patent published in 2008 - IPC C04B35/468 

FIELD: electricity.

SUBSTANCE: invention relates to pyroelectrical materials used in 8 to 14 microns IR radiation sources without cooling. The said ceramic pyroelectrical material contains polycrystalline barium titanate of strontium with alloying additives. The material containing MnO, Dy₂O₃, ZnO at the following ratio of components, percent by weight, i.e. MnO - 0,05-0,1;_{Dy2O3 - 0.1-0.2; ZnO - 0.05-0.15; barium titanate of strontium - the rest, are the said alloying additives.}

EFFECT: the material features high pyroelectrical factor; high quality; low dielectric permeability and low temperature of roasting.
