Disclosed are methods for forming boron nitride-containing aggregates that exhibit improved wear by attrition, and resulting filled polymers that exhibit significantly improved thermal conductivity. The boron nitride-containing aggregates are prepared according to a method that includes wet granulating boron nitride powder with a granulation solution to form wet boron nitride-containing granules; and drying the wet boron nitride-containing granules to cause evaporation of solvent in the granulation solution, thereby forming boron nitride-containing granules. Sintering achieves the desired boron nitride-containing aggregates.

Disclosed is a gas sensing material for methylbenzene detection. Specifically, the gas sensing material includes a nanocomposite of Cr.sub.2O.sub.3 and ZnCr.sub.2O.sub.4. The content of Cr in the nanocomposite is from 67.0 at. % to 90.0 at. %, based on the sum of the contents of Cr and Zn atoms. The gas sensing material is highly selective to methylbenzenes over other gases and is highly sensitive to methylbenzenes. Also disclosed are methods for preparing the gas sensing material. The methods facilitate control over the composition of the gas sensing material and enable rapid synthesis of the gas sensing material at low temperature. Also disclosed is a gas sensor including the gas sensing material.

Heat-expandable microspheres including a thermoplastic resin shell and a thermally-vaporizable blowing agent encapsulated therein. The thermoplastic resin is produced by polymerizing a polymerizable component containing (A) a nitrile monomer including acrylonitrile and methacrylonitrile, (B) a carboxyl-group-containing monomer, and (C) a monomer copolymerizable with the nitrile monomer (A) and the carboxyl-group-containing monomer (B). Further, the amount of the acrylonitrile in the nitrile monomer (A) ranges from 0.1 to 9 wt % based on the nitrile monomer (A). Also disclosed are hollow particles manufactured by heating and expanding the heat-expandable microspheres; a composition containing a base compound and at least one particulate material selected from the heat-expandable microspheres and the hollow particles; and a formed product manufactured by molding or applying a coat of the composition.
