Box furnace, tube furnace, high temperature furnace, electric heating furnace, vertical furnace, horizontal furnace, resistance furnace, etc. Ten years'experience in kiln and electric furnace production is trustworthy.

GWL series high temperature electric furnaces and vacuum electric furnaces have played a great role in target sintering technology. The atmosphere is adjustable, the pressure of electric furnaces can be adjusted, and the temperature control accuracy of electric furnaces is high-grade. Some domestic companies choose high-cost hot isostatic pressing technology. This technology can strengthen the pressing and sintering process, reduce sintering temperature, avoid the increase of grain size, so as to obtain excellent physical and mechanical properties. But there are some defects such as high production cost, long production cycle, simple cracking and low density.

Some use atmosphere sintering method to obtain high density ITO target through controlling sintering atmosphere during sintering process. Atmospheric sintering can be produced in large quantities successively, with lower cost and less equipment input than hot pressing. However, it requires higher requirements for ITO powder and suitable atmosphere sintering technology.

Because of the high demand for atmospheric pressure, it is dangerous to sinter at high temperature, and the cost of sintering is also high. Atmospheric pressure sintering was the mainstream technology of ITO target sintering in Japan at that time. It was also the direction of domestic efforts at present. Some companies were experimenting in this field, and no company had put into practice.

Generally speaking, hot isostatic pressing or cold isostatic pressing is usually used in the production of ITO target materials in China. The product quality is not high. It does not break the requirements of R FT-LCD in downstream industry. The products are limited to producing low-end T N conductive glass and some STN products.

The above is a detailed description of the technical advantages of high temperature electric furnace in ITO target sintering technology. If you have more questions about high temperature electric furnace, you can contact us directly.
