Examination of Behavior from Selected Foundry
Foundry sand is, according to the authors of,defined as granular refractory material with grains of sizes in a range from 0.02 mm to 2 mm. The most important foundry sand used is silica sand. The main component is In this study, spent foundry sand (SFS) was treated and used as a source to synthesis sodium silicate. Initially, SFS was subjected to calcination (C-SFS) followed Synthesis and characterisation of sodium silicate from spent foundry

Břuska et al. [ 10] studied the influence of grain shape and size on the expansion behaviour of silica foundry sands. The results showed higher expansion for fraction 0.355–0.5 mm than fraction 0.25–0.335 mm of the same silica sand type. Thiel et al. [ 11] investigated the effect of various factors like grain size, grain shape, grain sizeCrystalline silica has a higher melting point (1610 °C) than iron, copper or aluminium and other common metals. This enables castings to be made by pouring molten metal into moulds made from silica sand and a binder. The physical and chemical characteristics of the sand are important. In the past naturally clay bonded moulding sands were used.Foundry sand Silica and Moulding Sands Association (SAMSA
