The ferroelectric porcelain composition and the ferroelectric which uses that applied element

摘要

Poisonous Pb is not used and the ferroelectric which is superior in sinterring characteristic porcelain composition and the nonlinear optics element which uses that are offered. General system (Ba_{1-x-ySr xCa y}) it is displayed with ₂ Ag_{1-dNb5O15-d/2}, the main component and the general system aMnO which possess tungsten bronze structure₂ +bSiO2 (however a and b show each weight section for the aforementioned main component 100 weight section.)So the secondary component which is displayed is contained, the description above x, y, a, b and d are each 0.1x+y0.8, a+b5 and 0d0.6.
