Solid State Synthesis of Calcium Carbide from Ca Rich Wastes
Calcium Carbide is an advanced ceramic obtained by chemical reaction of calcium and carbon. The calcium carbide has a nominal formula of CaC2 and a molecular weight of 64,0992 g/mol. The Brinell hardness of calcium carbide is 80 HB. The pure composition is colorless, but there is a color from black to grayish white in the production methods in the arc furnace and atmospheric furnace. This change according to temperature and impurity rate. It is density is 2.22 g/c3 and melts at 2160 °C (inert atmosphere), decomposing at 2300 °C. The main uses of calcium carbide are acetylene gas and calcium cyanamide production. In addition, calcium carbide is used in iron and steel in desulphurization, as a strong deoxidant in steel crucibles, in agriculture in the ripening of fruits and lighting cartridges are used as fuel. Calcium carbide has two wide-using production methods. In these methods, CaCO3 and CaO are used as calcium source; coke and anthracite coal are used as carbon source. Calcium rich wastes have a large area in the world, by the way we will use calcium rich wastes as source of calcium. Chemical composition of calcium rich wastes are as follows; seashells (oysters, mussels, shells), eggshells, cement, fish bone etc. Seashells are rich in calcium carbonate which contain about 96% calcium carbonate in their chemical composition. In this study, seashells might be used as a rich waste for production of calcium carbide synthesis.
