Properties | Bentonite

Bentonite vitrification temperature is higher than other clays Therefore, when used as an additive, it makes green sand more durable, and, in particular, more resistant to heat stress Surface properties (coagulation– absorption – adsorption) Bentonite absorption – adsorption properties are determined by the high specific surface andthe mechanical properties of castings? Which physical properties are also affected adversely by porosity? Pores are, in effect, internal discontinuities that are prone to cracking and crack propagation Thus, the toughness of a material will decrease as a result of porosity Furthermore, the pres­MetalCasting Processes and Equipment; Heat Treatment
