AbstractThis aim of this research is study the effect of adding different percentages of magnesium hydroxide, kaolin and water on the production of refractory magnesite brick by use transformer process. Firstly transformative process carried out on the magnesium hydroxide and kaolin to obtain fine particle, after that mixture fine particle Burn in electric furnace at temperature (1000 oC ) for (2 hr ). The mixture Formed by using semi dry pressing with (10)% water under pressure (500 Kg/cm2) to obtain forming sample we carried out drying process ,and we can many test from inspection for obtain porosity, density, Water absorption, specific weight and more properties compressive strength . We fined finish refractory brick from light type where the resulted density is equal to ( 1.33 gcm3 ) and suits applications that need to lightness weight with durability.
