Synthesis of New Trioctahedral Mg-Smectite
New trioctahedral Mg-smectites were synthesized hydrothermally from homogeneous Mg–Si precipitates having a wide range of compositions, i.e., from Mg=3.2 to 6, vs. Si=8 in the atomic ratios. Dispersed solutions of the synthetic smectites formed transparent gels possessing good rheological properties.
