Abstract: Pnictide thin films, particularly phosphorus, grown on III-V semiconductors, particularly InP, GaP, and GaAs, are amorphous and have a novel layer-like, puckered sheet-like local order. The thin films are typically 400 Angstroms thick and grown preferably by molecular beam deposition, although other processes such as vacuum evaporation, sputtering, chemical vapor deposition, and deposition from a liquid melt may be used. The layers are grown on the <100> <110>, and surfaces of the III-V crystals. The pnictide layer reduces the density of surface states, and allows the depletion layer to be modulated, the surface barrier reduced, the electron concentration at the surface increased, and there is a decrease in the surface recombination velocity and an increase in the photoluminescence intensity.

Abstract: High phosphorus polyphosphides, namely MP.sub.x, where M is an alkali metal (Li, Na, K, Rb, and Cs) or metals mimicking the bonding behavior of an alkali metal, and x=7 to 15 or very much greater than 15 (new forms of phosphorus) are useful semiconductors in their crystalline, polycrystalline and amorphous forms (boules and films). MP.sub.15 appears to have the best properties and KP.sub.15 is the easier to synthesize. P may include other pnictides as well as other trivalent atomic species. Resistance lowering may be accomplished by doping with Ni, Fe, Cr, and other metals having occupied d or f outer electronic levels; or by incorporation of As and other pnictides. Top contacts forming junction devices doped with Ni and employing Ni as a back contact comprise Cu, Al, Mg, Ni, Au, Ag, and Ti. Photovoltaic, photoresistive, and photoluminescent devices are also disclosed. All semiconductor applications appear feasible.

Abstract: A fast-setting magnesium phosphate one-component adhesive/grout is used to bond tiles, e.g. ceramic tiles, to a substrate, e.g. sheet-rock. The grout comprises an activator prepared by e.g., mixing diatomaceous earth with at least a sufficient amount of an ammonium phosphate solution to form a paste then heating the paste to coat the pores of the diatomaceous earth and result in a dry solid which is then milled to yield the activator, magnesium oxide, diammonium phosphate, boric acid, and sufficient water to form a paste. This grout is applied to the surfaces to be bonded which are then brought together to form a composite which is allowed to set at ambient temperatures forming a durable bond in about three hours.

Abstract: The monofluorophosphate compatibility of dicalcium phosphate dihydrate can be improved in processes in which a slaked lime slurry is reacted with phosphoric acid to form a monocalcium phosphate solution to which is added magnesium oxide, additional lime slurry and pyrophosphoric acid with later removal of the dicalcium phosphate dihydrate. The improvement involved adding the magnesium oxide at 0.3%-2% and adding 0.1%--less than 0.5% of trimagnesium phosphate to the recovered dicalcium phosphate dihydrate.

Abstract: An improved process for preparing potassium metaphosphate is provided which comprises reacting potassium ions, preferably from the carbonate or bicarbonate, with phosphare ions in an amount sufficient to provide a K/P molar ratio ranging from about 0.85 to about 0.95 substantially in the absence of metal ion other than potassium under heat for a period of time and at a temperature sufficient to convert the potassium and phosphate ions to potassium metaphosphate but insufficient to overconvert. A product of higher viscosity can be obtained by dissolving the potassium metaphosphate in sodium bicarbonate rather than using other sources of sodium ion, particularly when the potassium metaphosphate is prepared with potassium bicarbonate or potassium carbonate.

Abstract: A filter cake formed of a glass precursor material and impregnated with a normally leachable toxicant can be heated, preferably with at least one other glass precursor material, at a sufficiently high temperature to form a molten composition which solidifies, upon cooling, to form a glass. The normally leachable toxicant becomes fixed within the glass rendering it substantially more non-leachable allowing for a more environmentally sound means for disposal, e.g., by landfill techniques. The process can be used to treat the arsenic sulfide-impregnated filter cake derived from the manufacture of food grade phosphoric acid.
