The AR grade magnesium oxide mainly used for reagent industry, other chemical engineering or reactive intermediates, for example, used for standard reagent, the constituent of ehrlich ‘ s reagent to decompose the sample . What’s more, it used for pharmacy, rubber and oil prodution industry. The AR grade magnesium oxide belongs to one of the high-end magnesium oxide in this field. It is relatively complex to manufacturer this product. Compared with ordinary magnesium oxide, the product value is higher.
The AR grade magnesium oxide is the purity of chemical reagent, and belongs to the second. The tag of it is bronze red, and used for the common test solution in general-analysis test . The principal component of it has a high content, high purity and low impurity. It is appropriate for proximate analysis and chemical experiment. For the specific purity, the different products have different requirements. The AR means that the purity level of reagent. It is also the difference between content and purity.
The AR means the reagent used for assay determination. The impurity is very few and get out of the assay determination. The CP(chemically pure) means the reagent used for general chemical test. The impurity was less and get out of the experimental requirements as well.
