| 20080260625 | Fine Particulate Titanium Dioxide, and Production Process and Use Thereof - A high-purity ultrafine particulate titanium dioxide with a reduced fluctuation of the adsorbed water content which is a large mass fluctuation factor in a fine particulate powder body, is provided. The fine particulate titanium dioxide has a BET specific surface area of 10 to 200 m | 10-23-2008 |
| 20090188701 | Inorganic powder, resin composition filled with the powder and use thereof - The present invention relates to an inorganic powder having a frequency-size distribution with multiple peaks, wherein the peaks are present at least in the particle size regions from 0.2 to 2 μm and from 2 to 63 μm, preferably with the maximum particle size being 63 μm or less, the average particle size being from 4 to 30 μm, and the mode size being from 2 to 35 μm. The inorganic powder of the present invention is useful as a filler for a high thermally conductive member in electronic component-mounted circuit board required to have electrical insulating property and heat radiating performance, in that a heat radiating member comprising the powder can have thermal conductivity, the powder can provide a resin composition having excellent withstand voltage characteristics for forming an insulative composition into a thin film and can be filled in the resin composition at a high density so as to improve heat radiating performance of the resin composition. | 07-30-2009 |
