  • Dead Burned Magnesium Oxide (DBM) for Refractory Applications

    Refractory materials maintain physical and chemical stability at high temperatures. Dead burned magnesium oxide (DBM), also known as Periclase, which is produced in shaft and rotary kilns at temperatures over 1500oC, has reduced chemical reactivity and therefore is suited to refractory applications.

  • Magnesium Oxide as a Crop Nutrient Supplement

    Seventeen nutrients have been identified as essential for plant growth. Without these nutrients, plants cannot complete their life cycles. Magnesium (Mg) is considered a "macronutrient" – those of the 17 nutrients required in relatively large quantities.
