Bentonite is utilized in foundry to bind the sand grains into desired shapes. Bentonite helps in retaining the mechanical shape of the mould by making the particles of sands adhere to it and also making the surface impermeable. Strength and fusion point are the two important properties desired for selecting bentonite. Primary use is in the production of non-ferrous castings.
