High purity Magnesium oxide is produced by the calcination of magnesium carbonate or magnesium hydroxide or by the treatment of magnesium chloride with lime followed by heat. Calcining at different temperatures produces magnesium oxide of different reactivity. High temperatures 1500 - 2000C diminish the available surface area and produces dead-burned (often called dead burnt) magnesia, an un-reactive form used as a refractory. Calcining temperatures 1000 - 1500C produce hard-burned magnesia which has limited reactivity and calcining at lower temperature, (700-1000C) produces light-burned magnesia, a reactive form, also known as caustic calcined magnesia. Although some decomposition of the carbonate to oxide occurs at temperatures below 700C, this appears rapidly reversible due to absorption of carbon dioxide from the air.

*MgO is lightly burned high-purity magnesia that is available for a variety of uses.
*MgO #150 is a high-active product..
*MgO P and KS are pharmaceutical-grade products.
*MgO KS is a granular type. It has good flow-ability and helps to improve productivity.
*MgO PSF is a fine-powder type of average particle size (1um). It contains less metal elements such as Fe, etc. It has a high purity and whiteness.

We also offer High Purity Magnesium oxide of the Grade HP Series, having consistent stable quality and characteristics.

Packing: Net weights are 25kg, 20kg and 10kg. Products are packed in multilayer bags or in drums, with a separately sealed polyethylene inner bag.

REQUIREMENTS
Labeling: Indicate whether it is Light Magnesium Oxide or Heavy Magnesium Oxide.
Identification A solution of sample in 2.7 N hydrochloric acid gives positive tests for Magnesium, Appendix IIIA.
Assay Not less than 96.0% and not more than 100.5% of MgO after ignition.
Acid-Insoluble Substances Not more than 0.1%.
Alkalies (Free) and Soluble Salts Passes test.
Arsenic Not more than 3 mg/kg.
Calcium Oxide Not more than 1.5%.
Lead Not more than 4 mg/kg.
Loss on Ignition Not more than 10.0%.

TESTS
Assay: Ignite about 500 mg of sample to constant weight at 800° _ 25° in a tared platinum crucible, accurately weigh the residue, dissolve it in 30.0 mL of 1 N sulfuric acid, boil gently to remove any carbon dioxide, cool, add methyl orange TS, and titrate the excess acid with 1 N sodium hydroxide. From the volume of 1 N sulfuric acid consumed deduct the volume of 1 N sulfuric acid corresponding to the content of calcium oxide in the sample taken for the assay. The difference is the volume of 1 N sulfuric acid equivalent to the MgO in the sample taken. Each milliliter of 1 N sulfuric acid is equivalent to 20.15 mg of MgO and to 28.04 mg of CaO.
Acid-Insoluble Substances Mix 2.0 g of sample with 75 mL of water, add hydrochloric acid in small portions, with agitation, until no more of the sample dissolves, and boil for 5 min. If an insoluble residue remains, filter it through a suitable tared porous-bottom porcelain crucible, wash well with water until the last washing is free from chloride, ignite at 800°_ 25° for 45 min, cool, and weigh.
Note: Avoid exposing the crucible to sudden temperature changes.
Alkalies (Free) and Soluble Salts Boil 2 g of sample with 100 mL of water for 5 min in a covered beaker, and filter while hot. Add methyl red TS, and titrate 50 mL of the cooled filtrate with 0.1 N sulfuric acid. Not more than 2 mL of the acid is consumed. Evaporate 25 mL of the filtrate to dryness, and dry at 105° for 1 h. Not more than 10 mg of residue remains.
Arsenic Determine as directed under Arsenic Limit Test, Appendix IIIB, using a solution of 1 g of sample in 10 mL of 2.7 N hydrochloric acid.
Calcium Oxide Dissolve about 400 mg of sample, accurately weighed, in a mixture of 3 mL of sulfuric acid and 22 mL of water. Add 50 mL of alcohol, and allow the mixture to stand overnight. If crystals of magnesium sulfate separate, warm the mixture to about 50° to dissolve them. Filter through a suitable tared, porous-bottom porcelain crucible, previously washed with 2 N sulfuric acid, water, and alcohol. Wash the crystals on the porous disk several times with a mixture of 2 volumes of alcohol and 1 volume of 2 N sulfuric acid. Ignite the crucible and contents at 450° _ 25° to constant weight. The weight of calcium sulfate so obtained, multiplied by 0.4119, gives the equivalent of calcium oxide in the sample taken for the test.
Note: Avoid exposing the crucible to sudden temperature changes.
Lead Determine as directed under Lead Limit Test, Appendix IIIB, using a solution of 1 g of sample in 20 mL of 2.7 N hydrochloric acid, and 4 _g of lead (Pb) ion in the control.
Loss on Ignition Transfer about 500 mg of sample, accurately weighed, into a tared, covered, platinum crucible. Ignite at 800° _ 25° for 15 min, cool, and weigh.
