A New Low-Expansion Composite in Lead Iron Niobate-Lead Titanate System

A New Low-Expansion Composite in Lead Iron Niobate-Lead Titanate System

A composite prepared between lead titanate (PT) and lead iron niobate (PFN) exhibits low thermal expansion coefficient (α) over the temperature range 300–673K. X-ray, DTA, and dilatometric measurements have been used to identify the optimum sintering condition, retaining the individual constituent i...
