摘要： The invention (Figures 1-10) relates to a method for making a high energy beam-sensitive glass article exhibiting insensitivity and/or inertness to actinic radiation, ie glass articles which are darkened and/or colored within a thin surface layer of, eg about 0.1-3 µm upon exposure to a high energy beam, electron beam, and ion beams in particulr, without a subsequent development step, and which need no fixing to stabilize the colored image, since both the recorded image and the glass article are insensitive to radiation in the spectral range of UV and/or longer wavelengths. More particularly, the instant invention is concerned with Ag⁺ ion-exchanged glass articles having base glass within alkali metal silicate composition fields containing at least one of the oxides of transition metals which have one to four d-electrons in an atomic state. Whereas the base glass composition can be varied widely, spontaneous reduction as well as photo-reduction of Ag⁺ ions are inhibited and/or eliminated due to the presence of said transition metal oxides in the glass article. The product of the invention is suitable for use as recording and archival storage medium and as phototools. The recorded images and/or masking patterns are updatable, can be any single color seen in the visible spectrum, and is erasible by heat at temperatures about 200°C.

摘要： This invention is directed to a method for heat treating a sheet of a potentially photochromic glass to cause the growth of silver halide crystals therein which impart photochromic properties thereto, wherein the heat treated sheet will be essentially free from thermal deformation and surface defects, and the photochromic properties exhibited therein will be essentially uniform across the area of the sheet. The method involves first placing a sheet of potentially photochromic glass on top of a sheet of carrier glass that exhibits a softening point at least 50°C higher than the temperature at which the potentially photochromic glass will be heat treated, and thereafter subjecting the stacked sheets to the heat treatment temperature desired for growing silver halide crystals in the glass.

摘要： There is disclosed a method of producing a photochromic glass having a reduced transmittance for ultraviolet radiation while having substantially unimpaired photochromic properties. The method comprises providing a combination of 0.1-1.0% CeO 2 and 0.1-1.5% Sb 2 0 3 and/or As 2 0 3 as part of the glass composition. In an embodiment utilizing minimal silver content, the glass article in thicknesses of 1.3 to 2.0 mm. can be chemically strengthened to surpass the impact specification imposed by the Federal Food and Drug Administration for eyewear, will transmit less than 0.2% of radiation having wavelengths between 290-315 nm, and will demonstrate a darkened luminous transmittance at 20°-25° below 35% and a fading rate such that after five minutes the luminous transmittance. These glasses consist essentially of:
