fine-grain ceramics
解釋
細粒陶瓷-
The influence of burning system on the properties and structure of the ceramic capacitors has been studied under the certain temperature system, the optimum sintering temperature of the ceramics was primarily decided by the content of bi2o3 ? 3tio2. the sintering temperature dropped with the adding of bi2o3 ? 3tio2. at the range of suitable sintering temperature, slow heating and low temperature sintering can obtain fine grain and dense structure. it results in the improving of the breakdown voltage for the middle - high voltage ceramic capacitors
研究了燒成工藝制度對電容器陶瓷性能和結構的影響，結果表明：在一定的升溫保溫時間下，瓷料的最佳燒結溫度主要取決于組成中bi _ 2o _ 3 ? 3tio _ 2的含量， bi _ 2o _ 3 ? 3tio _ 2含量的增加將降低燒結溫度；在合理的燒結溫度范圍內，慢速升溫和低溫燒結將有利於得到細晶緻密結構，從而改善中高壓陶瓷電容器的耐壓強度。 -
