Abstract
The present invention is related to a magnesium oxide particle aggregate with the requirement of a first inflection point diameter is more than 0.30×10-6 to 0.60×10-6 m, a particle void volume is 0.50×10-3 to 0.90×10-3 m3·kg-1, and a micropore volume is 0.04×10-3 to 0.11×10-3 m3·kg-1 in the cumulative intrusion volume curve of said particle by having controlled particle aggregation structure so that the solid phase-solid phase reaction between magnesium oxide and the SiO2 film on the surface can be appropriately controlled.
