Lead-based electroceramics such as Pb(Zr. Ti)O3 (PZT) and its derivatives have excellent piezoelectric. pyroelectric and energy storage properties and can be used in a wide range of applications. Potential lead-free replacements for PZT such as potassium sodium niobate (KNN) and sodium bismuth titanate (NBT) have a much more limited range of useful properties and have been optimized p... https://www.balboasurfandsstylers.shop/product-category/mugs/
