The nano size ceramic powders are produced via an aqueous low temperature process that allows for binary and tertiary oxide compositions with controlled stoichiometries. They serve both separately and together in an array of products including thin film and multilayer ceramic capacitors positive temperature coefficient resistors and varactors. The sol gel synthesis of barium strontium titanate ceramics 793 was to apply the sol gel method for preparation of bst powders and utilize the sol gel derived ceramic powders for sintering bulk ceramic materials with the ba sr ratio of 60 40 bst60 40. The obtained bst ceramics were characterized in terms of the.

Tpl offers a range of titanate powders with controlled size and chemistry. Strontium titanium trioxide cas number 12060 59 2.
