ceramic heating beads for ceramic heater pads/PWHT
Alumina Ceramic Beads is manufactured by dry press method and sintered at temperature upto 1650 C. All the material is prepared by Gongtao. The production is under careful material selection of high grade alumina spray drying granulation from what we call calcined alumina, thus the quality stability is maximally ensured. It enjoys high temperature resistance, excellent insulating property, and efficient thermal conductivity and heat transfer. Thanks to its property, the ceramic beads is widely used as components of flexible ceramic heating pad and channel heaters at operation of pre and postweld heat treatment; Welding process, stress-relieving, ship-building, other heat-resistance-environment. Compared with hot press method
Advantages: Higher density, higer surface finish and unifomity than heat press cast method, excellent thermal condictivity and heat transfer, resistance against thermal shock and mechanical abuse.
Application: As ceramic parts of flexible pad and channel heaters at operations of pre and postweld heat treatment; Welding process, stress-relieving, pre-heating & post heating, ship-building, other resistance-heating environment.

Customized Heterotypic Technical Ceramics
AIZA is a Lianyungang based Sino-Foreign joint venture corporation. It is a Chinese producer of calcined alumina and a manufacturer of alumina ceramics, such as alumina ceramic ball, alumina ceramic cylinder, alumina wear tile, ceramic insulator, ceramic element, ceramic beads, and other insulation ceramics with self-prepared material as well as German and Japanese material.
Since its creation, AIZA has served most of Chinese customers, Nanjing Huade, Zhuzhou Xianghuoju, and Chaozhou Sanhuan, which are eminent manufacturer of spark plug and advanced ceramic in China. Its "TCH" brand calcined alumina is well accepted by our customers.
In 2008, AIZA purchased 70 key equipment from Shanghai Morgan Matroc after its closure in China. The equipment includes isostatic press machine, dry press machine, hot press cast machine, ball mill, alumina spray prilling tower (centrifugal and pressure), polishing machine, etc. The equipment has been successfully installed in our factory by the end of 2008. Now, AIZA have succeeded in establishing itself as sole Chinese manufacturer of ceramic nozzle by isostatic dry bag pressing process. Besides, the most experienced technical engineer of former Shanghai Morgan Matroc also joined us, which is the precious source of our confidence of ensuring products quality.
