A METHOD FOR THE PRODUCTION OF OXIDE WHISKERS OF THE ELEMENTS TI, BE, MG, CA, ZN, B, AL, RARE EARTH METALS, SI, SN, V, ZR, SB, CR, MN AND FE OR MIXTURES THEREOF BY CONTACTING A COMPOUND OF THE AFOREMENTIONED ELEMENTS WITH A MELT OF AT LEAST ONE SALT OF A SULFUR-CONTAINING OXYACID CAPABLE OF FORMING A VOLATILE ANHYDRIDE, UNDER THE REACTION CONDITIONS. OPTIONALLY THE MELT CONTAINS ADDITIONALLY AT LEAST ONE METAL HILIDE PREFERABLY AN ALKALI METAL OR ALKALINE EARTH METAL HALIDE. NORMALLY THE REACTION IS CARRIED OUT AT A TEMPERATURE OF BETWEEN ABOUT 600 AND 1200*C. THE OXIDE WHISKERS WHICH FORM IN THE MELT ARE EASILY SEPARATED FROM THE REACTION MIXTURE EITHER BY CENTRIFUGING OR FILTERING THE HOT MELT OR BY REMOVING THE WHISKERS FROM THE REACTION BYPRODUCTS STILL IN THE MELT BY DISSOLVING SAID BYPRODUCTS IN WATER.
