 Electrical grade magnesium oxide is a stuffing material for sheath heating elements.
Magnesium oxide powders of high temperature are mainly used to produce stainless steel electrical heat tube (black)whose heating medium is air and through nitrogen treatment under 1050℃.
Magnesium oxide powders of middle-high temperature are used to produce electrical heat tube whose heating medium is air and its watt loading less than 6W/cm2, or use that to produce the stainless steel electrical heat tube (glow) whose heating medium is water or oil.
Magnesium oxide powders of middle-low temperature are mainly used to produce die-casting iron tube, or use that to produce stainless steel tube whose heating medium is water.
