摘要：
The invention relates to a novel process for the preparation of silicate comprising: reacting rice husk ash with a silicate precursor P1 to obtain a silicate S2 having a SiO2/MxO molar ratio MR2, in which the precursor P1 is either a silicate S1 having a SiO2/MxO molar ratio MR1 such that MR2>MR1, or a mixture of sand with metal hydroxide.
