Magnesium oxide or Periclase is a synthetic pure MgO mineral produced in electric arc furnaces by sintering Magnesite powder. Magnesium oxide is very refractory, and is used in the manufacture of bricks and crucibles for the metal processing industries, thermocouple insulation, etc.
Its low comparative cost, thermal conductivity and electrical resistivity properties at elevated temperatures make this material valuable for heating unit insulation. Crucibles and shapes, thermocouple insulation, infrared glass are other applications.
Slightly soluble in water, soluble in acids.
Here is a screenshot of side-by-side recipes in my account at insight-live.com. It takes 120 mag carb to source the same amount of MgO as 50 mag ox. I just made the two recipes, went into calculation mode and kept bumping up the magcarb by 5 until the chemistry was the same. Note the LOI of the magcarb version is 40. This one would certainly crawl very badly.
