Chromite Sand Testing
Typical foundry grade chromite sands will show a weight gain of 0.5 to 1.0 in a standard LOI test. • To avoid oxidation reactions, chromite sands can be heated under an inert atmosphere such as nitrogen. Under these conditions a high quality foundry chromite sand will experience a minimal weight loss of 0 to 0.2%
