ル％であることを特徴する赤外線透過ガラスである。However, among the lanthanide elements, there are neodymium and cerium that exhibit absorption in the infrared region, and it is extremely difficult to separate these substances from other lanthanide elements, making it difficult to obtain high-purity raw materials. However, even if glass could be obtained, it would be very expensive, and it was not easy to obtain glass with excellent infrared transmission properties. In addition, since thorium is a radioactive element, there are problems in practical use. In view of this, it is an object of the present invention to provide a new glass that does not have the above-mentioned problems and has excellent infrared transmission characteristics. 26 to 39 mol% of yttrium fluoride, and 2 to 7 mol% of yttrium fluoride.

、熱に安定なガラスが得られることを見出した。As a result of various studies on additive components to replace lanthanide elements and thorium for glasses whose main components are zirconium fluoride and barium fluoride, we found that by using yttrium fluoride as one of the components, it has excellent infrared transmission characteristics and heat resistance. It was discovered that a stable glass can be obtained.

た。The vitrification range of the ternary glass consisting of zirconium fluoride, barium fluoride, and yttrium fluoride is 57 to 69 mol % of zirconium fluoride, 26 to 39 mol % of barium fluoride, and 2 to 7 mol % of yttrium fluoride. It was found that the composition range satisfies the condition of %.
