    摘要: Glass composition having a high absorption of X-radiation, particularly in the wavelength region from 0.3 - 0.7 A, for use in fabricating high voltage vacuum tube glass envelopes. The glass compositions are a type of lead oxide containing glass which can be characterized as having an aggregate content of barium oxide with antimony oxide and cadmium oxide in excess of 10% by weight and further having an aggregate content of lead oxide with barium oxide, antimony oxide and cadmium oxide in excess of 55% by weight.

    摘要: Glass filters and their use in controlling transmission of radiation is disclosed. The filters have a sharp transmission cut off within the ultraviolet region of the spectrum and also withstand high temperatures and severe heat shock. They are produced from a fused silica glass having a composition consisting essentially of silica and 1-25 percent R2O5 wherein the R2O5 consists of 0-5 percent Nb2O5 and/or 0-25 percent Ta2O5. The transmission cut off may be shifted across the ultraviolet transmission range by varying the amount of additive.
