Abstract: Skeleton nanoparticles and method of forming the same. The skeleton nanoparticles comprise silica shells. Each of the silica shells has a shape of a cubic frame formed of six faces as a whole. The cubic frame is hollow inside and pores are formed between quadrilateral silica frames on respective faces of the cubic frame. The method comprising: coating an organic acid on surfaces of calcium carbonate particles; dispersing the organic acid-coated calcium carbonate particles in an organic solvent that dissolves a part of the organic acid in the organic acid-coated calcium carbonate particles, and further mixing a silicon alkoxide and a base catalyst to form silica-forming particles by forming the silica shell along an edge of the calcium carbonate particles; and dissolving the calcium carbonate at an inside of the silica-forming particles by an acid treatment.

Abstract: An electromagnetic wave absorber comprises an electromagnetic wave absorber molded element, plate-shaped sintered ferrite, and a metal plate. The molded element incorporates a tile-shaped base portion and a wedge-shaped apex portion disposed on the base portion. The molded element is formed by injecting slurry into a mold, the slurry being obtained through mixing a molding material for the wave absorber with water, and curing the slurry. The molding material includes a magnetic material, an inorganic fiber and an inorganic binder. When these ingredients are mixed with water, the molding material first exhibits fluidity and then a curing reaction in a temperature range of 1 to 40° C.
