【Abstract】 A series of experiments between wollastonite and acid show that the product characteristics relate to some technical conditions such as the reaction speed,reaction time,the final pH value of neutralization etc.At the same time,it is discovered that if the technical conditions are suitable,the silica with 400～600m 2/g can be produced.更多还原
