Abstract:
The present invention provides a method of preparing a carbon fiber-reinforced silicon carbide composite material, wherein carbon nanotubes are formed in the composite material, and then metal silicon is melted and infiltrated into the composite material, so the amount of unreacted metal is reduced and the strength of the composite material is improved, and provides a carbon fiber-reinforced silicon carbide composite material prepared by the method.
Abstract:
The present disclosure relates to a thermal storage material containing a hexanary composition of NaNO3—NaNO2—KNO3—KNO2—Ca(NO3)2—LiNO3 for lowering a melting point of molten salts.
Abstract:
The present invention relates to a method for manufacturing granulated bentonite including adding sand, alumina or graphite to a bentonite raw material, heating the resulting mixture to 700 to 1,200° C., and grinding a bentonite molded body formed by heating to produce granules of uniform sizes.
