Reactive magnesium aluminate spinel

Product introduction:
  Reactive magnesium aluminate spinel is made of imported industrial alumina and light burned magnesia then ground after calcined at suitable temperature. Besides good sinterability,it can also effectively improve the flowability and construction performance of castables. While reduce the sintering temperature of products, it can increase aggregate and matrix's bonding strength, products' densification, anti-slag and anti-spalling.

  Varieties of HS7 and HS9 can be available according to the alumina content.
