摘要

The present invention relates to a method for manufacturing low temperature sintered lead-free piezoelectric ceramics with an excellent electric field induced strain properties and, more specifically, provides a composition for low temperature sintered lead-free piezoelectric ceramics with excellent electric field induced strain properties represented by the following chemical formula 1: (1-x)Bi_0.5(Na_(1-y)K_y)TiO_3-x illite. In the chemical formula 1, x is a real number of 0.01 = x = 0.05 and y is a real number of 0.15 = y = 0.25. The present invention provides a method for manufacturing low temperature sintered lead-free piezoelectric ceramics with excellent electric field induced strain properties, offering a bismuth (Bi) based piezoelectric ceramics material different from a conventional lead based PZT family ceramics material which is harmful to humans and causes environmental pollution, thereby being eco-friendly, and mixes illite with a bismuth (Bi) based BNKT family ceramics material to manufacture lead-free piezoelectric ceramics, thereby being able to provide piezoelectric ceramics showing high electric field induced strain rate even at low temperature.
