TM-NB Series Ultrafine Reactive a - Alumina Specially for Castables

TM-NB Series Ultrafine Reactive a - Alumina Specially for Castables

Features:
    Its primary crystal is very small. It has good filling property and sintering activity. Aqueous slurry has good thixotropic fluidity. It can improve the sintered density, flexural and compressive strength of castables at high temperature. It can also enhance the castbles’ resistance to abrasion, corrosion and erosion. 
Applications:
    It can be used in castables of low cement, ultra low cement or no cement and shaped or unshaped refractory materials, etc
