摘要： A glass, glass-ceramic, or ceramic bead is described, with an internal porous scaffold microstructure that is surrounded by an amorphous shield. The shield serves to protect the internal porous microstructure of the shield while increasing the overall strength of the porous microstructure and improve the flowability of the beads either by themselves or in devices such as biologically degradable putty that would be used in bone or soft tissue augmentation or regeneration. The open porosity present inside the bead will allow for enhanced degradability in-vivo as compared to solid particles or spheres and also promote the growth of tissues including but not limited to all types of bone, soft tissue, blood vessels, and nerves.

摘要： A method and apparatus of reclaiming hazardous inorganic wastes to produce an environmentally benign abrasive for use in loose grain processes, as a coated or bonded abrasive, or as a polishing grain. A tough and useful abrasive, with a MOH hardness of 7 to 8, is manufactured from emission control dusts of the aluminum industry or sludges from other industries, and may include small amounts of lead and cadmium oxides as toughening agents. The abrasive particles are sized by air sifting or by water sedimentation separating methods. The process for the manufacture of abrasive material comprises the steps of removing soluble salts from a waste stream by hot water extraction; using a computer matrix to group the waste stream into different batches for mixing with other glass-making materials to form a batch mixture; oxidizing the organic compounds contained in the batched mixture; melting the batch mixture to form a glasseous substance; and fritting the glasseous substance to form the abrasive. The process preferably uses a glass melter that will oxidize organics; a scrubber to recapture vaporized heavy metal oxides and particles of the glass-making materials; and an oxygen injection system ensure thorough burning of organics. Certain sodium compounds may be added to reduce the melting point of the batch mixture. An abrasive formed by the process of the invention may comprise the following components by weight: 48-56% silica; 18-30% alumina; 6-12% NaO; 6-12% CaO and MgO; 2-4% Fe.sub.2 O.sub.3 ; and 0.1-1% PbO.

摘要： Material, such as, for example, sealed double bags of asbestos containing waste or ash from infectious waste or toxic material or radioactive waste, is transferred into a glass melt of a furnace. Gas bubbles released into the melt form a gas curtain which causes enhanced mixing of the material to accelerate the dissolution of the components of the added material. The presence of the gas bubbles reduces the cross-section of the molten glass through which current passes, which in turn increases the electrical resistance of the glass melt and therefore increases power generation of the melt or power density at constant current. A highly oxidizing hot region is produced under the location where the material is introduced into the furnace. Drawn off glass is shaped and quenched into at least two sizes of approximate spheres. The spheres are cooled sufficiently fast to be thermally tempered and have a surface compressive strength level above 5000 psi.

摘要： Wate asbestos is converted into a glass by maintaining within an electrical glass melting furnace a body of molten glass at a temperature above the decomposition temperature of asbestos; supplying asbestos to the furnace by a conveyor discharging above the body of molten glass so that the asbestos falls onto the molten glass and becomes decomposed and melted into glass; and withdrawing molten glass from the furnace at a temperature of at least 1000.degree. C. The asbestos is advantageously mixed with cullet and a melt accelerator and fed into the furnace by means of a screw mixer/conveyor. The furnace is advantageously operated at a pressure less than atmospheric pressure.

摘要： Striation-free, refractory-type glass tubing can be manufactured by placing particulate, crystalline, refractory materials in a tube of refractory glass having a sealed end. The tube is evacuated to withdraw gases and the vacuum is maintained. The sealed end of the tube is heated to its softening point and the particulate materials contained therein will melt, thereby converting these materials into a vitreous condition. Softened pieces are then broken off and substantially gas-free bodies of vitreous, refractory glasses having substantially no reentrant portions are formed. The majority of the surfaces are smooth and rounded. These bodies are then fed into a melter of conventional design at atmospheric pressure and substantially striation-free, refractory-type tubing is drawn.

摘要： Hollow microbeads of glass are produced during a number of operating phases in which an upwardly directed hot gas flow is produced in a firing chamber by firing a vertical furnace. The firing chamber is continuously charged with microparticles of a starting glass material and the microparticles are expanded in the hot gas flow into the hollow microbeads. Expanded hollow microbeads are discharged out of the firing chamber with the gas flow through a gas outlet at the upper end of the vertical furnace. Between successive operating phases there is respectively provided a charging break, during which the charging of the firing chamber with the microparticles is suspended. In these charging breaks, the microparticles remaining in the firing chamber are respectively removed from the firing chamber.
