  • Patent number: 5395806
    Abstract: A novel alkaline earth metal carbonate product for use as a raw material in the glass manufacturing process is disclosed. The alkaline earth metal carbonate becomes a part of the liquid phase in the glass furnace more readily and at a lower temperature; it decomposes to release carbon dioxide gas more rapidly so that all of the gas can escape from the molten glass more easily. Using these alkaline earth metal carbonate compositions, the production capacity of a glass furnace is increased.

  • Patent number: 5378665
    Abstract: Ceramic yttrium aluminate fibers are produced by processes that result in the formation of a microcrystalline ceramic oxide structure. In one process, a stoichiometric amount of a yttrium alkoxide is mixed with an aluminum alkoxide to produce a homogeneous mixture in an alcohol solvent. Following the addition of an alkoxide precursor of ZrO.sub.2 or of HfO.sub.2, the optional addition of an alkoxide precursor of MgO, and the subsequent addition of an organic acid, hydrolytic condensation to produce a suitable sol is accomplished by adding water. A slight excess of yttrium alkoxide can be used instead of the MgO precursor. The viscosity of the sol is adjusted to form a tractable gel that is spun into fibers which, after curing and firing, are shown to be microcrystalline in form, the resulting fibers having a submicron average grain size. Strength and stability result from the presence of solid particles of partially stabilized zirconia or hafnia at the grain boundaries and the triple points.
