<p><P>PROBLEM TO BE SOLVED: To provide an infrared ray reflecting material which has a black color and excellent infrared ray reflecting ability. <P>SOLUTION: A multiple oxide represented by general formula: Me<SB>x</SB>Mn<SB>y</SB>O<SB>z</SB>(wherein, Me is at least one kind of metal selected from the group comprising Ca, Sr, Ba and Mg, the values of x, y and z are as follows; z>x>y, and y≥1.8) has a black-based color. The infrared ray reflecting material containing the multiple oxide has excellent infrared ray reflecting ability. The material is produced by a method comprising mixing an alkaline earth metal compound and a manganese compound each in a prescribed amount and firing the resulting mixture, or the like. It is possible to use the obtained multiple oxide by blending the multiple oxide with a coating material or a resin composition because the multiple oxide is powdery for various applications, for example, relaxation of the heat island phenomenon by applying the resulting blend on a roof or external wall of a building or on a road or pavement. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
