Abstract: Oxide-free metallic, alloy or intermetallic compound formed by coating a powder of at least one member selected from the group consisting of elemental metallic, alloy and intermetallic compound with an oxide-replacing metal. The oxide-free compound may be compacted without the addition of a liquid sintering agent and at temperatures below the melting point of the compound, under sufficient pressure to form a uniform, consolidated intermetallic body.

Abstract: An extremely effective agent for achieving optimum bonding between a nonprecious dental alloy and porcelain is painted onto the alloy in slurry form and fired to prepare the surface of the alloy for bonding to porcelain. The bonding agent includes major proportions of fine gold powder, porcelain, liquid flux and a minor amount of fine zirconium oxide. The liquid flux is a low fusing flux dissolved in a liquid vehicle, such as glycerine or an alcohol. Suitable fluxes are boron oxide and its salts. The flux reacts to the porcelain and with the oxides which are formed on the alloy during firing to produce a low solubility, highly tenacious, adherent intermediate layer of oxides to which porcelain will readily and firmly adhere during subsequent application and firing.

Abstract: A heating apparatus is disclosed. The heating apparatus, adapted for use in the manufacture of a dental product, is formed by an enclosure having a heated zone and a control area. Layers of insulation enclose the heated zone. A conveyor is disposed in the heated zone for moving the dental product to be treated through a temperature gradient. An infinite switch within the control area is adjustable to vary the speed of the conveyor. Further controls within the area energize the apparatus and permit alarm functions.
