This product is manufactured by growing crystal nuclei produced through a vapor-phase oxidation reaction of high-purity metallic magnesium vapor and oxygen. It features high-purity, ultra-fine particles, the primary particles of which are single crystals. Without mechanical grinding, which could introduce impurities, we can manufacture two grades by controlling the growth rate of crystal nuclei: 500A (particle size:* 45-60 nm) and 2000A (particle size: 190-240 nm).
* Particle sizes are calculated from BET specific surface area
