【摘要】：以三乙醇胺和硼酸为原料,甲苯为带水剂,合成了三乙醇胺硼酸酯;以三乙醇胺硼酸酯为前驱体在氨气气氛中烧结制得六方氮化硼颗粒。采用FTIR、XRD、SEM、NMR对中间产物和最终产物进行了表征。结果表明:以三乙醇胺硼酸酯为前驱体,在1 200℃下烧结4 h,可制得质量分数为94.3%、六方晶型良好,粒径达17.52μm的六方氮化硼颗粒;经过2 000℃高温精制后的六方氮化硼颗粒具有较高的结晶度和致密度,质量分数可达到98.5%,粒径可达到30μm以上。
[Abstract]:Triethanolamine borate was synthesized by using triethanolamine and boric acid as raw materials and toluene as water-carrying agent. Hexagonal boron nitride particles were prepared by sintering triethanolamine borate in ammonia atmosphere. The intermediate and final products were characterized by FTIR XRDX NMR. The results showed that triethanolamine borate was used as precursor. After sintered at 1 200 鈩，
