摘要 |
A spherical hydrotalcite compound of the present invention is represented by Formula (1) below, having a hydrotalcite compound peak in a powder X-ray diffraction pattern, having a specific surface area of at least 30 m2/g but no greater than 200 m2/g measured by a BET method, and having a secondary particle size median diameter of at least 0.5μm but no greater than 6μm on a volume basis measured using a laser diffraction type particle size distribution analyzer. (MgxZn1-x)aAlb(OH)c(CO3)d.nH2O (1) In Formula (1), a, b, c, and d are positive numbers, 0.5≰x≰1, 2a+3b−c−2d=0, and n denotes hydration number and is 0 or a positive number.
