摘要： The disclosure describes a method for producing bulk, particulate material that includes solid, generally ellipsoidal particles by dispersing irregularly shaped feed particles including about 60 to 100% by weight of at least one silicate-containing material selected from among wollastonite, alkali feldspar, plagioclase feldspar and nepheline. While maintaining the feed particles in dispersion, they are heated sufficiently to bring about at least partial fusion within at least the surfaces of the particles. This produces a bulk particulate product of which about 15 to 100% by volume is generally ellipsoidal particles. Also described are compositions of matter including solid particles, at least a portion of which are substantially glassy and generally ellipsoidal. At least a portion of these particles have been respectively formed from feed particles composed substantially of at least one silicate selected from among wollastonite, alkali feldspar, plagioclase feldspar and nepheline. The bulk particulate compositions contain about 15 to 100% by volume of the substantially glassy, generally ellipsoidal particles that are products of at least partial fusion of such feed particles.

摘要： The invention relates to a method of heat processing particles of glass. A first current of a mixture of a combustible gas and a gas capable of oxidizing the combustible gas is introduced into a substantially cylindrical chamber from its lower end. The combustible gas is ignited to form a flame in which the gases have a speed of less than 10 m/s. The resulting flame creates a heat processing zone in the chamber. A quenching zone is provided by a second current of gas introduced into the chamber adjacent the chamber side wall such that it swirls around the flame. Particles of glass are then introduced at the lower end of the chamber and these particles contact the flame in the heat processing zone and are then directed to the quenching zone where they are hardened and from which they are collected.

摘要： A powdered material and a process for producing the material are disclosed. The powdered material consists essentially of spherical particles selected from the group consisting of metals, metal alloys, ceramic glasses, crystalline ceramic materials, and combinations of these. The material is essentially free of elliptical shaped material and elongated particles having rounded ends. The material has a particle size of less than about 20 micrometers. The process for making the spherical particles involves mechanically reducing the size of a starting material to produce a finer powder the major portion of which has a particle size of less than about 20 micrometers. The finer powder is entrained in a carrier gas and passed through a high temperature zone at a temperature above the melting point of the powder to melt at least about 50% of the powder and form the spherical particles of the melted portion. The powder is then directly solidifed.

摘要： A vortex combustion furnace (1) for the production of glass beads or the like is generally cylindrical and has an outlet flue (24) at its upper end. A burner (13) at the lower end burns a gas/air mixture. Secondary air is introduced into the chamber through tangential air inlets (16) and creates a vortex (71) within the chamber. Tertiary air is introduced through a ring of angled nozzles (71) surrounding the burner further to swirl the flame. The vortex has a top-hat temperature profile with a central heating region with a temperature in excess of 1000.degree. C. and a surrounding cooling region with a temperature not much above ambient. Glass cullet is supplied to a fluidized bed (53) and then entrained in a pipe (44) to be injected into the chamber. The cullet follows a spiral path in the vortex, is heated, melts to form glass beads, is then cooled and finally is collected after striking the wall of the chamber.
