Refractories are non-metallic materials that are chemically and physically stable at high temperatures of above 1,000°F. The melting point of refractory materials is higher than 2,732°F; the melting point of highly refractory materials exceeds 3,092°F. Refractories are used in the linings of high-temperature furnaces, reactors, and other processing units. They act as a thermal barrier between a hot medium and the wall of the containing vessel, and also provide a chemical protective barrier against corrosion. Further, they also provide thermal insulation to the various high-temperature furnaces, incinerators, and boilers. Different refractories of various chemical compositions are manufactured using different minerals. The various end-use industries where refractories are used abundantly are iron & steel, power generation, cement, glass, non-ferrous metals, chemicals, petrochemicals, and paper & pulp. ________ Note: *Core competencies of the companies are covered in terms of their key developments, SWOT analysis, and key strategies adopted by them to sustain their position in the market.
