Abstract
Alkaline earth metal basic silicate particles having a silicate of an alkaline earth metal on the surfaces of the alkaline earth metal hydroxide particles, and having an SiO2/MO (M is an alkaline earth metal) molar ratio as a whole in a range of from 0.01 to 0.90. The particles are useful as a stabilizer for the chlorine-containing polymers.
