More Information
Summary: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 x 10<-6> to 0.60 x 10<-6> m, a particle void volume is 0.50 x 10<-3> to 0.90 x 10<-3> m *kg<-1>, and a micropore volume is 0.04 x 10<-3> to 0.11 x 10<-3> m *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.
