    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.
