【摘要】：以三乙醇胺和硼酸為原料,甲苯為帶水劑,合成了三乙醇胺硼酸酯;以三乙醇胺硼酸酯為前驅(qū)體在氨氣氣氛中燒結(jié)制得六方氮化硼顆粒。采用FTIR、XRD、SEM、NMR對(duì)中間產(chǎn)物和最終產(chǎn)物進(jìn)行了表征。結(jié)果表明:以三乙醇胺硼酸酯為前驅(qū)體,在1 200℃下燒結(jié)4 h,可制得質(zhì)量分?jǐn)?shù)為94.3%、六方晶型良好,粒徑達(dá)17.52μm的六方氮化硼顆粒;經(jīng)過(guò)2 000℃高溫精制后的六方氮化硼顆粒具有較高的結(jié)晶度和致密度,質(zhì)量分?jǐn)?shù)可達(dá)到98.5%,粒徑可達(dá)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，
