摘　　要：The special glass ceramics with ferroelectric main-crystalline phase are very usefullbecause of their good electro-optical effect, excellent high dielectric properties and low therm-al expansion coefficient. This kind of materials has been noticed since the 1960s. Withthe development of ferroelectric nanocrystallites and fine composite technology nowadays, itis desired to get ferroelectric nanocrystallites with better-controlled size and to prepare newcomposite systems. Overcoming agglomeration among ferroelectric ultrafine grains is nec-essary. So it is important in this field to get the ultrafine PbTiO₃ grains in situ confinedgrown in glass with better controlled size.
