| Abstract | ||
| This Research dealt with the possibility of exploiting magnesium hydroxide [Mg(OH)2] which extracted from sea water for preparation magnesia refractory bricks .This kind of bricks are utilized in lining of high temperature furnace, and for refractory application because of their a very high melting point (1200 C°), It does not oxidize and it has excellent resistance to attack by iron oxide and alkalis. Ten samples were used which contain different percentages of magnesium – hydroxide as well as some of dead–burned magnesia and magnesia–chrome and other additives. These samples were mechanically compacted under pressure of (1000) Kg/cm² and then burned up to (1200C°) within schedule-burned of (100C°) for each half an hour, and delaying time for two hours at the maximum temperature (1200C°). All samples tested for mechanical, physical, linear variation, porosity and density at Building and Glass Research Centre, which indicate to the possibility of manufacturing Magnesia Refractory Bricks of low porosity and high density. | ||
