Magnesium metal powder coated
The passivated magnesium powder is mainly used in the desulfurization production of steel. The “spherical” magnesium powder has a small angle of repose and good fluidity. It has a small amount in desulfurization, a short processing time, a fast reaction speed, and a molten iron bottom. The amount is small, the desulfurization effect is good, and the desulfurization depth is as high as 0.004%.

【Physical and Chemical Property and technique Standard.】
The passivation magnesium powder looks grey and white, and the granule shape is roundness or unequal roundness.
The burning point of passivation magnesium powder is between 560℃-600℃.
The fire retardant time of passivation magnesium powder is not less than 15 seconds at 1000℃.
The passivation magnesium powder should not contain impurity and agglomeration, but there can be a little passivation layer powder.
Checking Rules
- Using eyes to see the color, shape and other appearance of the passivation magnesium powder.
- Content of granularity, loose density, Mg, CaO, CaF2, MgO, P, S, H2O is checked according to set standard.
- The burning point and fire retardant time are checked according to special equipment and method.
- Sampling of passivation magnesium powder is according to bathes (each batch is 2.0tons), and there can also be spot-check to contentious product.
