摘要: The concomitant effects of adding varied amounts TiO2 and temperature heat treatment on the crystallization ZrSiO4 from SiO2–ZrO2 binary systems were investigated. results showed that t-ZrO2 phase is stabilized in amorphous SiO2 network, simultaneous occurrence along with tetragonal zirconia (t-ZrO2) → monoclinic (m-ZrO2) transition tends to activate reaction between m-ZrO2 yield at elevated temperatures. formation metastable ZrTiO4 also witnessed intermediate temperatures dependent content, its dissociation into their individual ZrO2 oxides resulted formation. Ti4+ occupancy Zr4+ lattice sites ensured enhanced ZrSiO4, limit determined as 9%. Excess discarded gets crystallized rutile (r-TiO2).
