簡單的介紹一種高技法花費工藝，那是剛玉耐磨陶瓷管的自蔓燃低溫離合解體法制造。該管從內到外分別由剛玉陶瓷、過渡層、鋼構成，陶瓷層是在二千二百攝氏度以上超高溫構成的致密剛玉瓷，陶瓷同鋼(gang)軌(gui)通(tong)過過渡(du)層構(gou)成結子(zi)的聯合(he)。
首先將無縫(feng)鋼(gang)軌放到離心計的管(guan)模(mo)內，在(zai)(zai)鋼(gang)軌模(mo)內。在(zai)(zai)鋼(gang)軌內加入鐵橘紅和(he)鋁(lv)粉混(hun)合物，這種混合物是所說的鋁熱劑。當離心計管模自轉到達一定的速率后，經一火星撲滅鋁熱劑，鋁熱劑立即本身熄滅，熄滅波快速滋蔓，在滋蔓時出現化工反應。
鋁(lv)熱(re)劑反(fan)(fan)(fan)應(ying)生成物(wu)(wu)(wu)為(wei)穩定型(xing)剛(gang)玉(yu)和鐵(tie)，并釋放出少許熱(re)量。這些熱(re)量如(ru)果是(shi)在(zai)絕熱(re)要求(qiu)下，絕熱(re)氣(qi)溫可到達三千(qian)(qian)七百五十(shi)(shi)七K和三千(qian)(qian)五百零九K，它使鋼軌內本來(lai)物(wu)(wu)(wu)料以及反(fan)(fan)(fan)應(ying)后的生成物(wu)(wu)(wu)，等于熔(rong)(rong)點(dian)為(wei)二千(qian)(qian)零四十(shi)(shi)五攝氏度(du)的剛(gang)玉(yu)也都全(quan)部(bu)變為(wei)熔(rong)(rong)液(ye)。由于反(fan)(fan)(fan)應(ying)十(shi)(shi)分快速，熔(rong)(rong)融反(fan)(fan)(fan)應(ying)在(zai)向心(xin)力的效用下，鐵(tie)的比例為(wei)剛(gang)玉(yu)瓷比例的2倍，較輕的剛(gang)玉(yu)瓷則散播在(zai)鐵(tie)的內層，較重的鐵(tie)被向心(xin)力甩(shuai)到鋼軌內壁。

Piezoelectric ceramic is mainly used for manufacturing the ultrasonic transducer, transducer, transducer, ceramic filters, ceramic, ceramic discriminator transformer, high voltage generator, an infrared detector, surface acoustic wave device, electro-optic device, ignition and detonation device and piezoelectric gyro.
Piezoelectric ceramic manufacture characteristic in ferroelectric ceramics under DC electric field on the polarization, so it has a piezoelectric effect. General polarized electric field is 3 ～ 5kV/mm, temperature 100～ 150° C, 5 ～20min. These three are the main factors affecting polarization effect. Better performance of the piezoelectric ceramics, such as lead zirconate titanate system ceramic, the electromechanical coupling coefficient can be up to 0.313～ 0.694.
