Abstract

A method for manufacturing barium zirconate particles includes providing a mixture of materials that includes barium, zirconium and a sintering aid, wherein the sintering aid includes at least one of barium tungstate, potassium niobate, tungsten oxide, barium molybdate, molybdenum oxide, potassium tantalate, potassium oxide, sodium niobate, sodium tantalate, sodium oxide, lithium niobate, lithium tantalate, lithium oxide, copper oxide, manganese oxide, zinc oxide, calcium zirconate and strontium zirconate; and heating the mixture of materials to produce barium zirconate particles that include the sintering aid.

Claims (3)

1. A material comprising:

a plurality of particles, wherein each of the plurality of particles includes barium zirconate and an additive in the amount of between about one percent and about four percent by weight of a total weight of the material, the additive including at least one of barium tungstate, potassium niobate, tungsten oxide, barium molybdate, molybdenum oxide, potassium tantalate, potassium oxide, sodium niobate, sodium tantalate, sodium oxide, lithium niobate, lithium tantalate, lithium oxide, manganese oxide, calcium zirconate and strontium zirconate.

2. The material of claim 1 , wherein the particles each comprise a perovskite crystal structure.
