摘要： A mixture comprising (i) an oxide, hydroxide or oxyhydroxide of aluminum, (ii) an aluminum-containing sulfate, (iii) an oxide or oxyacid of boron or an alkali metal salt thereof and (iv) an alkali metal sulfate is heated at a temperature of 900 to 1200° C to grow an aluminum borate whisker. In this process, the reaction is advanced apparently in the solid phase, and this process is advantageous over the conventional processes in that the yield is high and the isolation and purification of the reaction product is facilitated.

摘要： An aluminum borate whisker is prepared by heating and reacting aluminum sulfate and an oxide of boron, an oxyacid of boron or an alkali metal salt thereof in the presence of an alkali metal sulfate and an alkali metal carbonate. In this process, the reaction is advanced apparently in the solid phase, and this process is advantageous over the conventional processes in that the yield is high and the withdrawal of the reaction product is facilitated.
摘要翻译： 通过在碱金属硫酸盐和碱金属碳酸盐的存在下加热硫酸铝和硼的氧化物，硼的含氧酸或其碱金属盐并使其反应来制备硼酸铝晶须。 在该过程中，反应显着地在固相中进行，并且与常规方法相比，该方法的优点在于收率高并且促进了反应产物的取出。
