Non – Flammable Brick Using Magnesium Oxide

Abstract -. Magnesium oxide (MgO) bricks, also known as magnesia bricks, are a class of basic refractories characterized by their high melting point, excellent thermal stability, and superior resistance to basic slags. applications, including steelmaking, cement production, and non-ferrous metal refining. The performance of MgO bricks is influenced by several factors such as purity of raw materials, manufacturing processes, and the presence of additives like carbon or spinel-forming agents.. The manufacturing process involves the selection of high-purity magnesite or seawater magnesia, calcination, mixing with binders, shaping, and high-temperature sintering. Innovations such as direct-bonded, chemically bonded, and carbon-containing MgO bricks are also explored for their enhanced corrosion resistance and mechanical strength MgO bricks, including hydration susceptibility and thermal shock resistance, along with recent advancements aimed at improving their performance through nanotechnology, synthetic additives, and optimized microstructure design.
