摘要： PROBLEM TO BE SOLVED: To provide a metal doped silica-based glass foam which has high mechanical strength, and functions as a photocatalyst which enables efficient exhibition of a photocatalytic action by ultraviolet light and also visible light, as well as a method of manufacturing this metal doped silica-based glass foam and a cleaning device using the metal doped silica-based glass foam. SOLUTION: This metal dope silica-based glass foam is composed mainly of silica and includes 1 to 20 wt.% of titanium, 100 to 10,000 wt.ppm of nitrogen and 10 to 5,000 wt.ppm. of a total content of transition metal elements other than titanium. In addition, the bulk density is 0.05 to 1.2 g/cm 3 . The cleaning device including the silica-based glass foam, and the method of manufacturing this silica-based glass foam are provided.

摘要： PROBLEM TO BE SOLVED: To provide a silica container being producible at a low cost and having high dimensional accuracy and high durability and to provide a producing method of the same. SOLUTION: The producing method of the silica container includes such steps: (1) a preparing step to prepare first raw material powders being silica powders, second raw material powders which consist of amorphous silica, whose mean particle diameter is smaller than that of the first raw material powders and which are spherical and third raw material powders which consist of amorphous silica and whose silica purity is higher than those of the first and second raw material powders; (2) a step to make granules where the second raw material powders are coated with a binder; (3) a step to mix the first raw material powders with the granules of the second raw material powders; (4) a step to form a specified shape by introducing mixed powders into the inside wall of an outer mold having revolution symmetry; (5) a step to form a substrate by pressing the mixed powders formed to be the specified shape; (6) a step to bake the substrate under an oxygen-containing atmosphere and to remove strain later; and (7) a step to form a transparent silica glass layer on the inner surface of the substrate by melting the third raw material powders while spraying and supplying. The steps of (6) and (7) are performed in random order after the step of (5) is finished. COPYRIGHT: (C)2010,JPO&INPIT
