Filed: 1988-12-19
Abstract: PURPOSE:To obtain the aluminum borate whiskers in good yield with good productivity by heating the supplied aluminum sulfate and boric anhydride in the presence of the sulfate and carbonate of alkali metals to cause a reaction, and growing whiskers. CONSTITUTION:(A) Aluminum sulfate as the aluminum source component and (B) at least one kind of a boron anhydride source component (e.g. boron oxide) selected from the oxide and oxyacid of boron or its alkali metal salt are prepared. The (A) component and the (B) component are heated at 1000-1200 deg.C in the presence of an alkali metal sulfate (e.g. sodium sulfate) and an alkali metal carbonate (e.g. anhydrous sodium carbonate), allowed to react with each other, and grown to obtain aluminum borate whiskers.
