PbTiO{sub 3} (PT)-PbO-B{sub 2}O{sub 3} glass-ceramics were produced by a sol-gel process. Achievement of high PT content at levels unattainable by conventional glass-ceramics preparation methods was semiquantitatively shown. PT content was similar to the designed PT volume fraction and seemed rather unaffected by the composition of the glassforming component at a calcination temperature of 700 C. A higher ratio of PbO to B{sub 2}O{sub 3} in the glassforming component resulted in a low PT crystallization temperature, <500 C. PT crystals 1--2 {micro}m in size were obtained at calcination temperatures >600 C.
