    摘要: The glass compositions of the present invention contain at least 2.0 wt % Al.sub.2 O.sub.3 to give resulting glass fiber an acceptable chemical durability for product performance, but no more than 3.0 wt % to ensure the fiber maintains a relatively high biosolubility. The compositions further include relatively high amount of Na.sub.2 O+K.sub.2 O+MgO+CaO, which tends to increase fiber biosolubility and allows for the use of reduced amounts of B.sub.2 O.sub.3 in the composition. The glass compositions have KI values that generally equal or exceed a KI value of 40 and are suitable for rotary processing. The compositions have liquidus temperatures below about 1800.degree. F. and viscosities above 300 Poise at the liquidus temperature. For higher B.sub.2 O.sub.3 compositions the liquidus temperatures are below 1650.degree. F., and the viscosities are above 1,000 Poises at the liquidus temperatures.

    摘要: Irregularly shaped glass fibers and insulation therefrom comprise two different glasses having differing coefficients of thermal expansion. These glasses also have physical properties which allow current processes to fabricate them into insulation. The glasses also meet German recommendations regarding a KI value of 40 or above.

    摘要: Irregularly-shaped glass fibers and insulation therefrom comprising two different glasses having differing coefficients of thermal expansion. The irregularly-shaped dual-glass fibers exhibit a substantially uniform volume filling nature, and provide improved recovery and thermal conductivity abilities even in the absence of a binder material.

    摘要: Provided is a process for making metal coated non-crystallized, amorphous glass fibers. The process fiberizes a glass containing a metal oxide such as cuprous oxide. The process then heat-treats the fibers to form a semi-conductive layer of copper oxide on the surface. A subsequent reactive reduction step produces a semi-continuous film of metallic copper. This is conductive enough for many radar applications.

    摘要: Crystallization-resistant, low liquidus, fluoride glasses are disclosed which consist essentially of ZrF.sub.4, optionally HfF.sub.4, BaF.sub.2, at least one of CsF or NaF, preferably AlF.sub.3 and LaF.sub.3, and at least one of InF.sub.3, YF.sub.3 and GaF.sub.3. The glasses are of utility as optical components because of their high IR transmission.

    摘要: Ion exchangeable glass compositions containing from 50 to 90 mole percent GeO.sub.2, from 5 to 30 mole percent Al.sub.2 O.sub.3, from 3 to 30 mole percent Li.sub.2 O, up to 30 mole percent Na.sub.2 O and up to 30 mole percent K.sub.2 O are provided. In another aspect, minor amounts of anhydrous fluorides and chlorides corresponding to these oxides are added to the glass compositions to aid in water removal. Glass articles formed of the germanate glass compositions of the present invention are readily ion exchangeable when contacted with certain salts. Strengthened germanate glass articles are also provided having an inner tension region and an outer compressive surface layer which provide good mechanical strength for the formed glass article. The strengthened germanate glass articles are made using the ion exchangeable germanate glass compositions of the present invention. The compressive surface layer of the strengthened germanate glass articles are formed by contacting the surface of the glass article with a suitable salt, preferably a molten alkali salt, in an ion exchange process. The surface compressive layer of the strengthened germanate glass article has a lower concentration of lithium ions than the inner tension region and has a higher concentration of select ions provided by the salt bath.
