Antimony-containing inorganic composition of matter and method for preparing same
Abstract
Abstract A NEW COMPOSITION OF MATTER USEFUL AS A FLAME RETARDANT ADDITIVE IN PLASTICS, PAINTS, FIBERS, ETC IS PREPARED BY REACTING ANTIMONY TRIOXIDE OR AN ANTIMONY TRIOXIDE GENERATING COMPOUND WITH A SUBSTRATE COMPRISING HYDROUS SILICA OR A HYDROUS ALKALI OR ALKALINE EARTH METAL SILICATE IN A WEIGHT RATIO IN THE RANGE OF FROM 1:4 TO 1:1 ON AN ANTIMONY TRIOXIDE:SUBSTRATE BASIS, THE REACTION BEING CARRIED OUT BY CALCINING AN ADMIXTURE OF SAID COMPOUNDS AT A TEMPERATURE WITHIN THE RANGE OF FROM 400*C. TO 550* C. IN AN OXYGEN CONTAINING ATMOSPHERE. WHILE THE DESCRIPTION AND ILLUSTRATIONS WHICH FOLLOW ARE DIRECTED PRIMARILY TO THE USE OF THE ANTIMONY-CONTAINING INORGANIC COMPOSITION OF MATTER OF THIS INVENTION AS A FLAME RETRADANT ADDITIVE FOR PLASTICS IT HAS OTHER USES AS FOR EXAMPLE AS A CATALYST FOR PROMOTING POLYMERIZATION OF MONOMERS.
