Low-temperature and low-expansion glass-crystal composites by the formation of Perovskite lead titanate

Abstract: The development of low-expansion and low-temperature solder glass composites by the formation of Perovskite lead titanate was studied by the use of differential thermal analysis and thermal expansion measurements techniques. The thermal expansion coefficients of these composites containing Perovskite lead titanate of highly negative thermal expansion coefficient are predictable, at least in simple systems, by the existing theories of thermoelasticity.
