  • Semiconducting glass and article
    Patent number: 5158812
    Abstract: A family of lanthana borate glasses modified by iron oxide to become semiconducting. The glasses resist devitrification, exhibit bulk resistivities in the range of 10.sup.8 -10.sup.12 ohms-cm and possess other properties to make them particularly suitable for use in producing perforated plates for such applications as multichannel plates. The glass consist essentially of 40-55% by weight La.sub.2 O.sub.3, 25-40% B.sub.2 O.sub.3 and 10-30% Fe.sub.2 O.sub.3.

  • Alkali-free multichannel plate and glass
    Patent number: 5034354
    Abstract: There is disclosed a family of alkali-free, lead silicate glasses having properties that make them particularly suitable for use in producing perforated plates for such applications as multichannel plates. In addition to lead oxide and silica, the glasses contain ZnO, BaO, CaO and, under certain circumstances, MgO.

  • Fluoroborosilicate glass and clad article
    Patent number: 4973565
    Abstract: There are disclosed fluoroborosilicate glasses that are particularly adapted to being drawn with lead silicate core glasses to produce clad glass fibers useful in forming fiber optic bundles to be incorporated in night vision equipment. The cladding glass has a refractive index not over about 1.465 and a coefficient of thermal expansion not over about 80.times.10.sup.-7 /.degree.C. The clad fiber has a numerical aperture approximating or equal to one.
