Abstract
A nano-composite structure. A synthetic nano-composite is described having a first component including a fibrous structured amorphous silica structure, and a second component including a precipitated calcium carbonate structure developed by pressure carbonation. The nano-composite may be useful for fillers in paints and coatings. Also, the nano-composite may be useful in coatings used in the manufacture of paper products.
Claims15
A composition of matter, comprising:
- a nano-composite structure having
- (a) a fibrous amorphous silica component, said fibrous amorphous silica component provided in three-dimensional haystack configuration that presents a fibrous structure having interstitial spaces between amorphous silica fibers with inner layers and outer layers with irregular interlacing amorphous silica fibers or filaments which are fixed in relation to each other;
- (b) a crystalline calcium carbonate component, said crystalline calcium carbonate component comprising aragonite needle structures, said aragonite needle structures arising from said fibrous amorphous silica component;
- and
- (c) wherein said nano-composite structure has a major axis of length L in the range from about 10 microns to about 40 microns, and a surface area of from about 40 meters squared per gram to about 200 meters squared per gram.
