常温常压下三氯化硼11（B¹¹Cl₃）为无色发烟气体，可燃，有刺激性、酸性气味，遇水分解生成氯化氢和硼酸，并放出大量热量，在湿空气中因水解而生成烟雾，在醇中分解为盐酸和硼酸酯。三氯化硼11反应能力较强，能形成多种配位化合物，三氯化硼加热能和玻璃、陶瓷起反应，也能和许多有机物反应形成各种有机硼化合物。高纯三氯化硼11主要用于（硅）半导体器件制造工艺中的扩散掺杂，在高温下，经过分解生成硼杂质向硅中扩散，形成P型半导体，也可用于Al、MoSi₂、TaSi₂、TiSi₂、WSi等材料的干法蚀刻。
At normal temperature and pressure, boron trichloride(BCl₃) is colorless smoke gas, which is flammable, pungent, acidic odor. Boron trichloride decomposes into hydrochloric acid and boric acid and releases a lot of heat encountering with water, it generates smoke in wet air because of hydrolysis, and BCl₃decomposes into hydrochloric acid and boric acid ester in alcohol. Boron trichloride has a strong reaction ability and can form a variety of coordination compounds. Boron trichloride can react with glass and ceramic when heated, and it also reacts with many organic compounds to form a variety of organoboron compounds. High purity boron11 trichloride is mainly used for diffusion doping in the manufacturing process of (silicon) semiconductor devices. Boron impurities are generated through decomposition of BCl₃and diffuse toward silicon to form p-type semiconductor at high temperature. BCl₃ can also be used for dry etching of Al, MoSi₂, TaSi₂, TiSi₂, WSi and other materials.
