Houer (B, 03) Add approximately 0.5% silver halide and 0.015% copper oxide to 20% raw material and melt in a hot bath at 1500°C to create transparent glass. Next, add this to 5
When heated at 50°C, the steel and halogen combine to form silver halide particles, making it possible to produce photochromic glass that darkens as the amount of light increases.
この方法では、１５００℃１で高温の処理工程があり、
コストが腐くなるという欠点があった。This method involves a high temperature treatment step at 1500℃1.
The disadvantage was that the cost was high.
そこで、不発明の目的は、ゾル、ケル法の手法を用いる

ができるので、低コスト化が実現できる。Water and hydrochloric acid were added to a mixture of silicon tetraalkoxide, aluminum trialkoxide, and soteium alkoxide (or sodium alkyl group), and then silver halide was added, and the mixture was stirred thoroughly until the viscosity became high. By the way, it is added to a container, gelled, and contracted to form a dry gel. By heat-treating this dried gel at about 900° C., transparent glass and photochromic glass can be obtained. As described above, in the manufacturing method according to the uninvented method, the photochromic glass can be shaped by heat treatment at a considerably lower temperature than in the conventional method, so that cost reduction can be realized.
以下、実施例に従い、不発明の詳細な説明する。Hereinafter, the invention will be described in detail according to examples.

To a mixture of 1 tog (α16 mol) of soteium ethoxide was added 200 ml of ethanol, then 2322 ml of salt water bathing gold of 0.1 kg was added, and then 2.5 t of silver chloride (
0,017 mol) and 2.52 (1013 mol) of bromide@ were added. This bath liquid was stirred for 72 hours, and the highly viscous bath liquid before gelation was added to a Teflon petri dish. This was left at room temperature for gelation and shrinkage, and a dry gel was formed. When this dried gel was heated to a total temperature of 900° C. at a heating rate of 13° C./hr, a transparent crystal gel was obtained. By heating this to 550° C., growth of halogenated steel particles was observed, resulting in a glass exhibiting photocrocism.

きく貢献すると考えられる。As described in the Examples above, a photochromic glass similar to that of the conventional one was obtained with lower melting point than the conventional method of producing photochromic glass. Therefore, it is believed that the inventive photochromic glass (7) method will greatly contribute to cost reduction.
