The invention discloses a silicate product containing SiO2, Al2O3, Na2O, K2O, MgO and ZrO2. According to 100 parts by weight of SiO2, the content of Al2O3 is 15-28 parts by weight, the content of Na2Ois 13-25 parts by weight, the content of K2O is 6-15 parts by weight, the content of MgO is 7-16 parts by weight, the content of ZrO2 is 0.1-5 parts by weight, and according to the following formulathat M is 5-13 and equals to P1*wt(Na2O) plus P2*wt(K2O) plus P3*wt(MgO) plus P4*wt(ZrO2) minus P5*wt(Al2O3)*wt(Al2O3), wherein P1 is valued as 0.53, P2 is valued as 0.153, P3 is valued as 0.36, P4 isvalued as 0.67 and P5 is valued as 0.018. The invention also provides a chemically-enhancing method of the silicate product. The chemical-enhancing method provided by the invention has the beneficialeffects that in the chemically-enhancing process, ultrasonic treatment is adopted, or ultrasonic treatment and microwave treatment are adopted simultaneously, so that the Young modulus and the surface compressive stress value of the silicate product can be further increased, simultaneously the changing trend of the compressive stress value along with the depth and the depth of a comprehensive stress layer also can be controlled, and further, the spontaneous explosion or slow fracture after collision can be effectively prevented.
