<P>PROBLEM TO BE SOLVED: To provide a far infrared radiating ceramic which has a reduced manufacturing cost, is stable in nature, and is excellent in far infrared radiating ability near the body temperature of a human body, and to provide fibers, films and other moldings containing the ceramic. <P>SOLUTION: The far infrared radiating material is composed of a mixture of 40 to 50wt.% SiO<SB>2</SB>, 25 to 35wt.% Al<SB>2</SB>O<SB>3</SB>, 15 to 25wt.% F<SB>2</SB>O<SB>3</SB>, 1 to 5wt.% TiO<SB>2</SB>, 0.01 to 2wt.% ZrO<SB>2</SB>, and 0.01 to 1wt.% PtO<SB>2</SB>, and is produced by using silica stone, silica sand, diatomaceous earth, kaolinite, montmorillonite, etc., as silicon raw materials, alumina as an aluminum raw material, iron oxide as an iron raw material, titanium oxide as a titanium raw material, platinum alumina as a platinum raw material, and zirconium oxide as a zirconium raw material. <P>COPYRIGHT: (C)2007,JPO&INPIT |
