Abstract
A method is proposed for making a composite material based on a molecular mixture of polytetrafluoroethylene and SiO2 via absorbing the on thermal decomposition products of ammonium hexafluorosilicate and polytetrafluoroethylene in ammonia water. Using XRD diffraction analysis, it was evidenced that there is of SiO2 molecular distribution observed in the composite structure. An influence of the compound introduced upon the yield of fluorosilicon composite output from the gas phase was studied
