    摘要： Disclosed is a method of producing a barium-titanium-based ferroelectric glass using a containerless solidification process, such as an electrostatic levitation process or a gas levitation process, which comprises the steps of levitating a sample 1 of a barium-titanium-based compound by a levitating force of compressed air, heating the sample up to a temperature greater than its melting point (1330° C.) by about 100° C. to allow the sample to be molten, and, after maintaining the molten state for a given time period (at least several second), quenching the sample from a given temperature range (1400 to 1000° C.) at a cooling rate of about 103 K/sec, so as to allow the sample to be solidified while inhibiting nucleation and mixing of impurities from a container. The present invention makes it possible to provide a glass exhibiting an unprecedented, extremely large permittivity.

    摘要： For the preparation of high purity glass powder having a mean particle size of .ltoreq.10 .mu.m, glass powder having a larger particle size up to 300 .mu.m is ground to the desired particle size in a stirred mill with glass grinding elements in the presence of a grinding liquid comprising water or preferably a mixture of at least 50% by weight of water and at least one water-soluble, oxygen-containing organic compound having 1 to 5 carbon atoms in the molecule, e.g., tert.-butyl alcohol; the ground slurry is then frozen, and the solvent is subsequently removed from the frozen slurry by freeze-drying. A resultant glass powder with a mean particle size d.sub.50 of 0.5 to 2 .mu.m is particularly suitable as a filler for synthetic resins in the dental sector.

    摘要： A process for making small metal spheres encapsulated in an oxide glass. A metal compound, which decomposes to the elemental metal upon heating is mixed with oxide glass particles such that the final material contains from about 1 to about 15 percent of the metal by weight. The mixture is then heated to a temperature above the decomposition temperature of the metal compound as well as above the melting temperature of the metal wherein the oxide glass has a viscosity range of from 1 to about 5,000 poise. The mixture is then cooled to a temperature below the freezing point of the metal.

    摘要： Spherical glass beads are produced by isolating individual glass particles on a non-wetting ceramic block and heating the glass to a temperature at which the glass particles are drawn-up into spherical beads. The spherical beads, either coated or uncoated, may be employed as the carrier in an electrostatographic developer. The carriers are characterized by more uniform sizing and greater approximation to a spherical shape.

    摘要： A METHOD OF PRODUCING GLASS SPHERES OR BEADS FROM CRUSHED GLASS. THE METHOD INVOLVES APPLYING A RESIN BINDER TO THE SURFACES OF THE GLASS PARTICLES AND THEN APPLYING A COATING OF A FINELY DIVIDED SUBSTANCE, SUCH AS GRAPHITE. THE THUS COATED PARTICLES ARE DRIED AND ARE INTERMIXED WITH A MATRIX WHICH HAS APPROXIMATELY THE SAME SPECIFIC GRAVITY AS THE GLASS AND IS PRESENT IN ABOUT THE SAME QUANTITY BY WEIGHT. THE INTERMIXTURE OF COATED GLASS AND MATRIX IS THEN SUBJECTED TO EXTERNALLY APPLIED HEAT WHILE THE MIXTURE IS BEING CONVEYED THROUGH AN ELONGATED ROTARY CALCINER. THE CALCINER IS EFFECTIVE TO RAISE THE MIXTURE TO A TEMPERATURE WHICH PREFERABLY IS BELOW THE IGNITION POINT OF THE MATRIX BUT ABOVE THE SOFTENING POINT OF THE GLASS. THE MIXTURE IS MAINTAINED AT THE SELECTED TEMPERATURE FOR A SUFFICIENT PERIOD OF TIME TO CAUSE THE GLASS TO SOFTEN TO SUCH AN EXTENT THAT ITS SURFACE TENSION, AIDED BY THE ROLLING MOTION OF THE CALCINER, CONVERTS THE PARTICLES INTO SPHERICAL FORM. AFTER SUCH SPHEROIDIZATION OF THE GLASS HAS BEEN ACHIEVED, THE MIXTURE IS DISCHARGED ONTO A SHAKER SCREEN OF SUITABLE MESH, ADAPTED TO RETAIN THE GLASS SPHERES ON ITS UPPER SURFACE BUT TO PERMIT THE MATRIX TO PASS THROUGH ITS OPENINGS INTO A CATCH BASIN. THIS ENABLES REUSE OF THE MATRIX WITH ANOTHER QUANTITY OF COATED GLASS, AND IT SERVES TO RAISE THE TEMPERATURE OF THE LATTER TO A SUBSTANTIAL EXTENT BEFORE IT IS INTRODUCED INTO THE CALCINER. WHEN IT IS DESIRED TO STRESS THE GLASS SPHERES TO OBTAIN BEADS OF GREATER STRENGTH, THE SPHERES ARE DELIVERED FROM THE SHAKER SCREEN TO AN OIL BATH WHERE THEY ARE QUENCHED. IF DESIRED, THE SPHERES MAY THEN BE SEPARATED FROM THE OIL AND DRIED TO A CONDITION READY FOR SHIPMENT OR STORAGE. MOST OF THE OIL USED IN THE QUENCHING STEP IS RECOVERED AND COOLED FOR REUSE IN THE PROCESS.
