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

exact text as granted — not AI-modified
1 .- 16 . (canceled) 
     
     
         17 . A mixture of materials comprising:
 barium, zirconium and 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.   
     
     
         18 . The mixture of materials of  claim 17 , wherein the barium and zirconium are in the form of barium zirconate. 
     
     
         19 . The mixture of materials of  claim 17 , wherein the barium is in the form of barium carbonate and the zirconium is in the form of zirconium oxide. 
     
     
         20 . A material comprising:
 a plurality of particles, wherein each of the plurality of particles includes barium zirconate and 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.   
     
     
         21 . The material of  claim 20 , wherein the particles each comprise a perovskite crystal structure.
