Caustic Calcined Magnesite Powder
Fine powder produced by calcining natural magnesite at moderate temperatures to yield reactive magnesium oxide with some residual CO2. Classified under HTS 2519.90.20.00 as caustic calcined magnesite, distinct from dead-burned or fused magnesia due to its lower sintering temperature and higher reactivity.
Reactive Caustic Magnesite 90% MgO
Lightly calcined magnesite powder with 90% MgO content, used primarily in fertilizer production and acid neutralization. Falls under HTS 2519.90.20.00 because it's produced from natural magnesite via caustic calcination, retaining reactivity characteristics.
