简单的介绍一种高技法花费工艺，那是刚玉耐磨陶瓷管的自蔓燃低温离合解体法制造。该管从内到外分别由刚玉陶瓷、过渡层、钢构成，陶瓷层是在二千二百摄氏度以上超高温构成的致密刚玉瓷，陶瓷同钢轨通过过渡层构成结子的联合。
首先将无缝钢轨放到离心计的管模内，在钢轨模内。在钢轨内加入铁橘红和铝粉混合物，这种混合物是所说的铝热剂。当离心计管模自转到达一定的速率后，经一火星扑灭铝热剂，铝热剂立即本身熄灭，熄灭波快速滋蔓，在滋蔓时出现化工反应。
铝热剂反应生成物为稳定型刚玉和铁，并释放出少许热量。这些热量如果是在绝热要求下，绝热气温可到达三千七百五十七K和三千五百零九K，它使钢轨内本来物料以及反应后的生成物，等于熔点为二千零四十五摄氏度的刚玉也都全部变为熔液。由于反应十分快速，熔融反应在向心力的效用下，铁的比例为刚玉瓷比例的2倍，较轻的刚玉瓷则散播在铁的内层，较重的铁被向心力甩到钢轨内壁。

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.
