Calcium aluminate cement (CAC) contents higher than 3wt% in refractory castables can
have some drawbacks in the various processing steps (mainly drying) and also in their …

In recent times nanotechnology has drawn significant attention in the field of refractory
research. Different nano-powders and colloidal suspensions have been utilized to improve …

Two types of magnesium-aluminate spinels, one commercially available as preformed
powder and the other prepared from cheaper precursors by the sol–gel route as a semidried …

Ceramic engineers have investigated the rheology of the refractory concrete to keep the
balance between the desired characteristics of castables and its flow demeanor. The …

A binder for refractory castables is a bonding material that bonds a loose powdery mix,
retains its shape after casting and allows the cast shape to set and harden for handling and …

This work provides a new source of binder system, ie, waste rice husk ash (RHA) derived sol
for unshaped refractories. A facile (alkali extraction) route is used to synthesize the sol from …

Calcium oxide (CaO) which originated from calcium aluminate cement (CAC, binder) in
alumina-magnesia refractory castables significantly deteriorates its high-temperature …

Abstract Development of high pure alumina castable is studied by using synthesized mullite
sol as the sole binder. Mullite sol is prepared by wet chemical route and is characterized by …

Abstract MgAl 2 O 4 nanoparticles (NPs) were prepared by sol–gel method using aluminium
nitrate, magnesium nitrate and citric acid as starting materials, phenolic formaldehyde resin …

Steel manufacturing technology has changed drastically in last few decades to meet the
demand of high purity and quality of steel from the steel users. The advancements in steel …
