03/09/2012 · The ESA 2011 additive does not produce additional gas evolution compared to sand alone (Figure 21). Effect on Core Density Additions of 5% of ESA 2011 additive decrease the weight of the core by about 10%. This means more cores can be produced from the same weight of mixed sand and that the cores are lighter and easier to handle.

Refractory Clay. Calcined Clay or Refractory clay is obtained by Calcining (heating) superior grade Clay at high temperature (from 850o C to 1600o C). This removes moisture and volatiles which thereby increases the Alumina content. Compared to an Alumina content of about 30% to 40% in raw Clay, Calcined Clay has an Alumina content of 40% to 60%.
