MAGNESIUM OXIDE FINE PARTICLE FLUID DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a magnesium oxide fine particle fluid dispersion with viscosity thereof at a low stable value even when stored in an extended period of time.SOLUTION: In a magnesium oxide fine particle fluid dispersion, magnesium oxide fine particles within a range of 1-40 mass% are dispersed in monohydric alcohol having 1-5 carbon atoms, and Dof a magnesium oxide fine particle measured by dynamic light scattering is within a range of 5-90 nm. The moisture content of the fluid dispersion is 9000 mass ppm or lower.
