How Measuring The Index Of Magnesium Oxide
First
test indicators, content, clarifying degree, hydrochloric acid insolubles,
water soluble content, burning weightlessness, chloride, sulfate, phosphate,
total amount of ammonia, carbonate and other impurities, such as sodium,
potassium, calcium, iron, copper, arsenic, zinc, barium and strontium, heavy
metals and other products, analysis of the above material is pure magnesium
oxide in order to test some of the indicators.
Different indicators of detection, in
different ways, such as the determination of the content of magnesium oxide is
said to take a certain amount of sample first, and then add a small amount of
water wet, drops to sample all dissolved with hydrochloric acid solution, to a
certain amount of volumetric flask, dilute to scale, adequate volume, with
ammonia and chrome black T reagent, using ethylenediamine tetraacetic acid
disodium to standard solution titration solution from purple to a pure blue,
calculated by the formula of magnesium oxide content.
The determination of other indexes is also
similar to the determination method of content, which requires taking a certain
amount of samples and calculating them in different ways and using different
calculation formulas.
Mei shen is the world's leading
producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic
compound. It is a white solid at room temperature. Magnesium oxide exists in
the form of periclase in nature and is a raw material for magnesium smelting.
Magnesium oxide is white or light yellow powder, odorless, tasteless, this
product is insoluble in water and ethanol, melting point 2852 ° C, boiling
point 3600 ° C, magnesium oxide has high refractory insulation properties. It
can be converted into crystal by burning at a temperature above 1000 ° C. If it
rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the
manufacture of metallurgy, smelting, advanced magnesia bricks, refractory
materials and moisturizing materials. It is also widely used in rubber, rubber
sheet, rubber products, pharmaceutical industry, food industry, plastic sheet
accelerator, glass fiber reinforced plastics and Surface coating of silicon
steel sheet, paper production, steel ball polishing, leather treatment,
insulation materials, grease, dyes, ceramics, desiccant, resin, flame
retardant, etc.
