ABSTRACT:
The present invention is related to a magnesium oxide particle aggregate with the requirement of a first inflection point diameter is more than 0.30×10−6to 0.60×10−6m, a particle void volume is 0.50×10−3to 0.90×10−3m3·kg−1, and a micropore volume is 0.04×10−3to 0.11×10−3m3·kg−1in 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 SiO2film on the surface can be appropriately controlled.
