Nano-Bonded Wide Temperature Range Designed Refractory
Designing high-performance refractory castables for aluminum and petrochemical applications is not a straightforward target as at their operation temperature range (800°C–1250°C) usual refractory binders show low-bonding effectiveness and also low sinterability. Taking this into account colloidal binders can anticipate the castable s densification and inhibit the drawbacks regarding the
