Reactive Alumina For High Alumina Castable

Being a customer centric organization, we are involved in manufacturing, exporting, trading and supplying a supreme quality range of Reactive Alumina For High Alumina Castable in Pune, Maharashtra, India.

High-alumina refractory castables with compositions in the systems CaOAl2O3 and CaOAl2O3SiO2 were studied using an ultrasonic technique. The technique allows in-situ, non-destructive measurement of Young's modulus from room temperature to 1600A C. Elastic and dilatometric properties were investigated in relation to phase changes (followed by XRD) and sintering phenomena. The conversion of CAH10, the hydration of still-anhydrous cement phases, and the dehydration of C3AH6 and AH3 are related with events in Young's modulus evolution. Addition of 1 wt% of silica fume strongly decreases the high-temperature mechanical properties.

Furthermore, we provide this Reactive Alumina For High Alumina Castable at very nominal rates.
