    Notes: Abstract Aluminum borate with Al to B ratio of 10 was treated with water steam at 750 ° C for up to 48 h. It was found that steam would change the pore size distribution and the surface area of the aluminum borate. It did not possess superior hydrothermal stability under severe conditions. This can be ascribed to high surface instability of transition materials especially for boron compounds. However, even when only a small amount of boron is incorporated into the alumina structure, the surface area of such material can be increased.
