The regularities of the process of interaction of amorphous potassium polytitanate with titanium oxide in the process of firing their mixtures taken with different content of components are investigated. The mechanism and sequence of phase transformations in the studied mixture are analyzed. It was found that the introduction of titanium oxide into potassium polytitanate leads to the formation of a denser ceramic structure consisting of compacted potassium hexatitanate nanofibers stabilized by TiO 2 crystals.
