Activated Alumina Powder

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
