Abstract
The present invention is related to a magnesium oxide particle aggregate with the requirement of a first inflection point diameter is more than 0.30×10to 0.60×10m, a particle void volume is 0.50×10to 0.90×10m·kg, and a micropore volume is 0.04×10to 0.11×10m·kgin 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 SiOfilm on the surface can be appropriately controlled.
