A composite material includes an aggregate which contains a first metal particle constituting a core and second metal oxide particulates surrounding the first metal particle and having an average primary particle diameter ranging from 1 to 100 nm.

Composite material, composite material substrate, composite material dispersed fluid, and manufacturing methods thereof

A structure having strong contact with solid particles comprising an assembly formed by secondary aggregation which is further aggregation of aggregates each formed by primary aggregation of primary particles each made of a metal and/or a metal oxide, wherein an average primary particle diameter of the primary particles is in a range from 1 to 100 &#x3bc;m, and, among void pores formed by the aggregates, a volume of void pores having pore diameters in a range within &#xb1;50% away from an average void pore diameter of the void pores is equal to or above 60% of a total volume of the void pores.

Structure having strong contact with solid particles, substrate having strong contact with solid particles, and manufacturing methods thereof

A molten-salt type catalyst is adapted for purifying particulate materials, which are contained in an exhaust gas emitted from an internal combustion engine and contain carbon. It includes a solid support and a catalytic ingredient. The catalytic ingredient is loaded on the solid support, and includes at least one member selected from the group consisting of silver nitrate, alkali metal nitrate, alkaline-earth metal nitrate and rare-earth nitrate. The molten-type catalyst can efficiently burn and remove the particulate materials even in a low temperature range.
