Abstract: A process is described for producing amorphous metal alloys wherein impure ferrophosphorus slag, a by-product from a phosphorus-producing electric furnace, is used to supply phosphorus, chromium, vanadium and iron values to such alloys by mixing it with iron and any other desired metalloid and/or elements to form a molten mixture, treating the molten mixture to a separation step to remove insoluble slag formed in said molten mixture, and rapidly cooling the molten mixture to below its vitrification temperature to form a solid amorphous metal alloy.

Abstract: Polymeric phosphonitrilic chlorides are produced from ammonia and phosphorus pentachloride in a continuous process in a plurality of reaction zones characterized by simultaneous addition of reactants and continuous withdrawal of product.

Abstract: Phosphonitrilic chloride polymers are continuously esterified in a process wherein a solution of phosphonitrilic chloride polymer in an organic solvent is concurrently fed into a reactor with an alkanol solution of an alkali metal alkoxide, and the product phosphonitrilic chloride ester is continuously withdrawn and separated.
