Talk about the low-temperature sintering of alumina ceramic

High purity wet chemical powder has been rapid development of a gel made ??very good in it. Because alumina ceramics sol his height is very stable, so a lot of metal ions are stable, he can be dehydrated to form a more symmetrical gel, he can also get more lively micronized mixed oxide. Here we should let Jiangsu Province Ceramics Research Institute to tell us about his  technique and process.

He will form a metal oxide-based solution glue, after hydrolysis of polymer materials, Jiangsu Province Ceramics Research Institute, dehydration during the evaporation into a gel, and the last is the low-temperature calcination reactive oxygen species. In the same metal ions inside, the acid salt solution and the organic glue is mixed into a solution, performing dehydration by evaporation into a gel, of course, also to be low temperature calcined. You can also direct quenching precipitation, let him become a gel, during the low-temperature calcination.

In fact, this chemical powder surface performance than active mechanical powder is much higher. We can also see that this ultrafine powder his raw material is not solely as a sintering temperature, can also be used as a high alumina ceramic material.(picture/text http://www.jiangsuceramics.com/
