Sintering plate corundum uses high pure industrial alumina and adds no additives during production. Other impurities such as iron, silicon and sodium are trace, except for a small amount of mechanical iron in crushing (iron can be removed by a magnetic separator).
The plate corundum for high purity corundum brick is better than molten corundum in terms of heat impact and spalling resistance. Sintered corundum has good thermal shock and spalling resistance, and has a certain number of closed holes. Spherical obturator effectively resists thermal shock and prevent cracks from spreading. The molten corundum has more openings and less obturators, and forms larger single crystals during slower cooling. These single crystals produce microcracks during fragmentation, thereby reducing thermal impact and stripping resistance.
The production process of high pure corundum brick is energy efficient and environmentally friendly than molten corundum. Melting corundum production is a famous energy-consuming enterprise, consuming 2300-3300 degrees per ton, while the comprehensive energy consumption of sintering board corundum is only one seventh to one tenth of the molten corundum. During the production of the molten corundum, large amounts of waste gas and slag were discharged. In the production of sintering board corundum, taking natural gas as the heat source, discharging no other waste gas and slag except the carbon dioxide in the natural gas.buy Aluminum Sulfate
