Acitvated alumina powder
The physicochemical index standards:Q/LINGS-SD A016-2017
Activated alumina powder is produced by activation roasting process,with hydraulical property.
Activated alumina powder main usage
- refractory castable
- advanced ceramic binder
- catalyst support
- medical absorbent and specific catalysts
