A small proportion is granulated, using rapid water and air quenching that results in the production of a vitrified fritlike product. Phosphorus slag is sometimes expanded (solidified with controlled quantities of water, air, or steam, which accelerate the process and increase the cellular nature of the slag), producing a lightweight product.
