PRODUCT DESCRIPTION:Our Reactiv Aluminas RA series
Reactive Alumina is specially designed for the production of high performance refractories where defined particle size, rheology and consistent characteristics are very important. YONAI adopts best alumina made in CHALCO as raw material and calcined in the tunnel kiln at strictly controlled temperature which is our patent technology as well as our grinding crafts.
We are proud to provide our RA series reactive alumina which have property as:
★Excellent particle size distribution will work as water reducer
★Will have ceramic bond and largely improve abrasive and mechanical performance.
★As grinded to super fine , RA can reduce the porosity can improve the mobility of castable
