Grinding and drying of a raw mixture containing aluminum trihydroxide with an average particle size of 50-130 mu m and a specific surface of 0.01-0.5 m 2>/g, after Brunauer-Emmett-Teller, and 0.1-20 wt.% of water comprises feeding the raw mixture into a grinding-drying aggregate; feeding a hot air flow with a temperature of 20-100[deg] C in the grinding-drying aggregate; and crushing the raw material in the aggregate. Independent claims are included for: (1) aluminum trihydroxide obtained by the above method; and (2) the preparation of a thermoset comprising incorporating aluminum trihydroxide in at least a crosslinkable liquid resin from an unsaturated polyester resin, epoxide resin or polyurethane to obtain a mixture of aluminum trihydroxide and liquid resin and crosslinking the obtained mixture. |
