Abstract:
Alumina having excellent electrolytic solution stability, a slurry containing the same, an alumina porous film using the same, a laminated separator, a nonaqueous electrolyte secondary battery and a method for manufacturing the nonaqueous electrolyte secondary battery are provided. Alumina is provided including one or more selected from K, Mg, Ca, Sr, Ba and La in the total amount of 200 to 50,000 ppm by mass, wherein a surface concentration of one or more elements is 0.5 to 20 at % in total. Alumina is provided in which in an infrared absorption spectrum of the alumina obtained by Fourier-transform infrared spectroscopy, a peak having an intensity larger than that of a baseline defined by a line segment connecting an intensity at 3,400 cm −1  and an intensity at 3,500 cm −1  and having a half width of 90 cm −1  or less, does not exist in a range of 3,400 to 3,500 cm −1 .

Claim (Index 3):
The alumina according to  claim 1 , wherein the alumina has a BET specific surface area of 1 to 20 m 2 /g, and the alumina is \u03b1 alumina.
