Due to the large quantity of magnesium oxide (MgO) located in Asia (especially in China), Middle East, the magnesium cement materials have been used for many years in these areas. That is also why most of the MgO board selling around the world are made in China.
In fact, the magnesium is a kind of metal with flammable and unstable characteristics, that is why sometimes it use for fireworks. But the magnesium also could use as good structures for airplanes or cars, such as the magnesium alloy.
When the magnesium combined with the Oxygen in the natural environment, after long time, it becomes a new material MgO, like the stone. So, magnesium oxide is generally getting from the mine. The MgO mine will be ground up into powder for making MgO board.
Now in the market, there are mainly two different formulas of MgO board. 
One is MgO board with Chloride: magnesium oxide, magnesium chloride (MgCl2), wood fiber, fiberglass mesh and additives.
One is Sulfate MgO Board: magnesium oxide, magnesium sulfate (MgSO4), wood fiber, fiberglass mesh and additives.
So, you could simple understand that the main difference is whether you use the magnesium chloride or magnesium sulfate. Why use the two different materials? Because the magnesium chloride is easy to absorb the moisture from ambient and lead to quality issues. Now the sulfate MgO board is becoming the first choice for most customers, like in the USA, Canada, Europe, Australia and so on.
