After drying,magnesium sulfite and magnesium sulfate are roasted in the regeneration process to decompose them,resulting in magnesium oxide and the precipitation of sulfur dioxide.The roasting temperature has a significant impact on the properties of magnesium oxide,and the suitable roasting temperature for magnesium oxide regeneration is 660-870℃.
With the continuous development of high-tech ceramics,rubber,plastics,catalysts,and environmentally friendly materials,the application of magnesium oxide crystal materials,especially high-purity oxygen materials(with a magnesium oxide content of no less than 98%),is becoming increasingly widespread.
