Abstract
Abstract This invention relates to a sol of ultra-fine particles of synthetic hectorite prepared by swelling and cleaving Li-hectorite having a formula of Li1/3Mg2-2/3Li1/3(Si4O10)F2 or Na-hectorite having a formula of Na1/3Mg2-2/3Li1/3 (Si4O10)F2 in water or an organic solvent.

A sol of ultra-fine particles of synthetic hectorite, prepared by swelling and cleaving Li-hectorite having the formula Li 1/3 Mg 2-2/3 Li 1/3 (Si 4 O 10 )F 2 or Na-hectorite having the formula Na 1/3 Mg 2-2/3 Li 1/3 (Si 4 O 10 )F 2 in water or an organic solvent, and ion-exchanging the Li or Na ions co-ordinated between the lattice layers of the hectorite with a non-hydratable cation selected from the group consisting of K + , Ag + , Cu + , Ba 2 + , Pb 2 + , Sn 2 + , Zn 2 + , Al 3 + , Bi 3 + and Sb 3 +
Claim 2
Dependent Claim
113 words
A sol of ultra-fine particles of synthetic hectorite, prepared by swelling and cleaving Li-hectorite having the formula Li 1/3 Mg 2-2/3 Li 1/3 (Si 4 O 10 )F 2 or Na-hectorite having the formula Na 1/3 Mg 2-2/3 Li 1/3 (Si 4 O 10 )F 2 in water or an organic solvent, and ion-exchanging the Li or Na ions co-ordinated between the lattice layers of the hectorite with a non-hydratable cation selected from the group consisting of K + , Ag + , Cu + , Ba 2 + , Pb 2 + , Sn 2 + , Zn 2 + , Al 3 + , Bi 3 + and Sb 3 +
Claim 3
Dependent Claim
37 words
A heat-resistant and insulating film-like product prepared by spreading the sol of claim 1 on a flat surface, drying it to remove the water or organic solvent therefrom, and removing the film-like product from the flat surface.
Claim 4
Dependent Claim
59 words
A heat-resistant and insulating film-like product prepared by mixing the sol of claim 1 with a filler selected from the group consisting of organic fibers, inorganic fibers, ceramic minerals and mixtures thereof, spreading the thus-prepared mixture on a flat surface, drying it to remove the water or organic solvent therefrom and removing the film-like product from the flat surface.
Claim 5
Dependent Claim
41 words
A heat-resistant and insulating film-like composite product prepared by coating the sol of claim 1 onto a substrate selected from the group consisting of metals, ceramics and organic films and drying the sol to produce a composite heat-resistant insulating film-like product.
Claim 6
Dependent Claim
61 words
A heat-resistant and insulating film-like composite product prepared by mixing the sol of claim 1 with a filler selected from the group consisting of organic fibers, inorganic fibers, ceramic minerals and mixtures thereof, spreading the thus-prepared mixture onto a substrate selected from the group consisting of metals, ceramics and organic films and drying the mixture to produce the film-like composite product.
