Materials comprising barium zirconate and methods for manufacturing thereofMaterials comprising barium zirconate and methods for manufacturing thereof description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090264275, Materials comprising barium zirconate and methods for manufacturing thereof. Brief Patent Description - Full Patent Description - Patent Application Claims
This application claims priority to copending U.S. provisional application entitled, “Ceramic Filler Material for Making Polymer-Ceramic Composites Transparent to Microwave Radiation,” having Ser. No. 60/853,174, filed on Oct. 20, 2006, which is entirely incorporated herein by reference. Radio frequency identification (RFID) technology is used in many applications to identify and determine the locations of various items. An example of RFID technology uses a passive RF device, also referred to as an RFID chip, embedded within or otherwise associated with an item. When the RFID device comes within range of a corresponding RFID transceiver, the presence of the RFID device is detected by the RFID transceiver. One limitation of such a system is that the RFID device may be embedded in the item, causing the material from which the item is formed to attenuate the RF signal between the RFID device and the RFID transceiver, thus limiting the range over which the REID transceiver can detect the presence of the RFID device. Therefore, it would be desirable to minimize any attenuation between the RFID device and the RFID transceiver. Materials comprising barium zirconate and methods for manufacturing such materials are disclosed. An embodiment of 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. An embodiment of a mixture of materials for manufacturing barium zirconate particles includes 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. An embodiment of barium zirconate particles includes 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. Other systems, methods, features, and advantages of the invention will be or become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the invention, and be protected by the accompanying claims. The invention can be better understood with reference to the following figures. The components within the figures are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the invention. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.
