A multi-component material is represented by the general formula (I): Ba.sub.(1-y-y) Pb.sub.y M.sub.x TiO.sub.3 (I) in which: M is Sr or Cd; x is the decimal fraction molar concentration of MTiO.sub.3, where x has a value equal to or greater than about 0.20 and less than or equal to about 0.75; and y is the decimal fraction molar concentration of PbTiO.sub.3, where y has a value greater than zero and less than or equal to about 0.40, and x+y is less than 1.0. In addition, a method of graphically estimating the composition of the multi-component material represented by the general formula (I) is disclosed herein. In a preferred embodiment, x has a value between about 0.28 and 0.66, and y has value greater than zero and less than or equal to about 0.34, while said material has a Curie point temperature of about 25.degree. C. or room temperature. These room temperature Curie point materials are useful in uncooled thermal imaging applications.

Multi-component материал представлен вообще формулой (i): Ба.суб.(й-ы-ba.sub.(1-y-y) Pb.sub.y M.sub.x TiO.sub.3 (I) в: М будет sr или cd; x будет концентрацией десятичной части молярной MTiO.sub.3, где х имеет значение равное к или greater than около 0.20 и less than or equal to около 0.75; и ы будет концентрация десятичной части молярная PbTiO.sub.3, где ы имеет zero значения greater than и less than or equal to около 0.40, и x+y чем 1.0. In addition, метод графически оценивать состав multi-component материала представленного вообще формулой (I) показан здесь. В предпочитаемом воплощении, х имеет значение между около 0.28 и 0.66, и ы имеет zero значения greater than и less than or equal to около 0.34, пока сказанный материал имеет температуру пункта curie около 25.degree. Температура C или комнаты. Эти материалы пункта curie температуры комнаты полезны в uncooled термально применениях воображения.
