Laponite RD / Magnesium lithium Silicate High light transmittance
1.?English Synonyms:
Silicic acid, lithium magnesium sodium salt;Lithium magnesium sodium silicate;Kieselsure,;Synthetic magnesium lithium silicate;Synthetic magnesium silicate
2. Description:
Magnesium lithium Silicate is a synthetic layered silicate. It is insoluble in water but hydrates and swells to give clear and colorless colloidal dispersions. At concentrations of 2% or greater in water, highly thixotropic gels can be produced.

?5.Gel mechanism:
This product is a three eight surface of the layered silicate minerals, when mixed with water, the powder rapidly expansion until the sheet separation.Due to the negatively charged surface of thin layers, with positive charge, after the separation of the sheet end are attracted to the other sheet dimension, resulting in the rapid formation of three-dimensional colloidal structure of the system, the increase of viscosity
