National Institute for Fusion Science and Gifu Prefectural Institute of Ceramics has been successful in bridging the science and technology by developing an idea of self-consistent isothermal barrier. It has certain dielectric constant and loss-tangent to be heated by microwave at 2.45GHz in keeping the equal temperatures and equal rising rates with the work pieces. The energy flow by radiation/convection balances between the work pieces and the inner most wall of the kiln. The thermal energy flux balances on the surface of work pieces, i.e. zero in total. Under such an ideal thermal insulation, work pieces get energy only by electric field of microwave and heat themselves uniformly. The stress free system realizes the rapid sintering.Through the development of the microwave kilns, energy consumptions were measured. Roughly speaking, it is the rapidity of microwave heating that saves the energy. It inhibits the grain growth and numbers and size of pores. We designed and manufactured more than ten microwave kilns for industries in 2001, including pure microwave roller hearth.

国家聚变科学研究所和岐阜县陶瓷研究所通过开发自洽等温屏障的想法成功地连接了科学和技术。它具有一定的介电常数和损耗角正切，在2.45GHz微波加热下，保持与工件等温度和等上升速率。通过辐射/对流的能量流在工件和窑的最内壁之间平衡。热能通量在工件表面上平衡，即总共为零。在这种理想的隔热条件下，工件仅通过微波电场获得能量并均匀加热。无应力烧结系统实现了快速烧结。通过微波炉的研制，对微波炉的能耗进行了测试。粗略地说，是微波加热的快速性节省了能源。它抑制晶粒生长和孔隙的数量和大小。2001年设计制造了十多台工业微波窑炉，包括纯微波辊道炉。
