<p><P>PROBLEM TO BE SOLVED: To provide heat-resistant aluminum hydroxide particles having both a high dehydration starting temperature and a sufficient dehydration amount which are difficult to achieve by the conventional aluminum hydroxide, a method for producing the heat-resistant aluminum hydroxide particles, and a resin composition, a prepreg and a laminated plate containing the heat-resistant aluminum hydroxide particles. <P>SOLUTION: The heat-resistant aluminum hydroxide particles are obtained by heat-treating aluminum hydroxide particles at 200-270°C in a fluorine-containing gas atmosphere to substitute part of the hydroxy groups of the aluminum hydroxide particles into fluorine. Alternatively, the heat-resistant aluminum hydroxide particles are obtained by treating aluminum hydroxide particles with a fluorine ion-containing solution to substitute part of the hydroxy groups of the aluminum hydroxide particles into fluorine, and then heat-treating the resulting particles at 200-270°C. There are also provided the method for producing the heat-resistant aluminum hydroxide particles, and the resin composition containing the heat-resistant aluminum hydroxide particles, the prepreg and the laminated plate. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
