The MAS products are high-performance sintered basic shaped refractories formulated with high-purity magnesia (or fused alumina) and synthetic magnesia-alumina spinel. Manufactured via high-pressure forming and high-temperature firing, MAS bricks exhibit excellent thermal shock resistance, structural strength at high temperatures, and outstanding resistance to slag attack. These bricks are widely used in critical zones of steel refining processes that demand superior resistance to thermal cycling, high loads, and corrosive slags.","itemId":"03de7683-a9ed-436c-a5b9-67ae9011c31d","fieldSchemaId":"5aca91c8-f9f8-4e20-ad57-68b28f197fc6"},{"id":"7560e64b-94f0-4474-954f-55770bcfb791","value":"Magnesia-Alumina Spinel Bricks
