What is magnesium activity?
Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation [1-3]. Magnesium is required for energy production, oxidative phosphorylation, and glycolysis.
What is the role of magnesia in cement?
It also gives hardness and strength to the cement. Magnesia: It also gives colour to the cement. Magnesia in excess makes the cement unsound. Sulphur: A very small quantity of Sulphur in the cement makes the cement sound.
Why magnesia is used in bricks?
Magnesia is widely used in the steel industry as a refractory brick. It is often impregnated with carbon (tar, pitch, graphite) to provide the best properties for corrosion resistance in environments of basic slags, particularly in BOF furnaces or slag lines of treatment ladles.

What is the Colour of magnesium ribbon?
Colour of magnesium metal is silvery white. Hold the magnesium ribbon with the help of a pair of tongs, light the magnesium and collect the ash of burnt ribbon in a china dish. It burns brilliantly and a white ash is left behind. Magnesium burns in air to form Magnesium oxide (MgO).
