Very high structure, hybrid amorphous silica products (geltates) having very high absorptivity, in which the hybrid silica product has a % carrying capacity DBP value greater than 76.0 and a linseed oil absorption value exceeding 250 cc/100 g, and a production methodology therefor.

Very high structure, highly absorptive hybrid silica and methods for making same

Very high structure, highly absorptive hybrid silica and method for making same

An amorphous silicate pigment having a pore volume of at least about 4.0 ml/g as measured by mercury intrusion, a BET surface area of at least about 300 m,/g, and an Al,O,content of about 2.0-10.0 wt % is provided. The invention can be successfully used in recording media coatings, particularly coatings for recording media used in ink jet printing systems.

High surface area silicate pigment and method

A method for stabilizing or inactivating a detrimental and moiety in curable, cross-linkable, and thermoplastic polymers which comprises mixing 100 parts by weight of acid moiety containing polymer with from about 0.1 to about 40 parts by weight of tricalcium aluminum hexahydrate and the resulting composition are disclosed.

Acid acceptor for polymers containing acid moieties

An improved method for the production of synthetic hydrotalcites having high purity (99+%) and small particle size (&lt;2 microns) is disclosed. This method used inexpensive and available reactants and is suitable for commercial scale production. A source of magnesium, such as magnesium hydroxide; a source of aluminum from a mixture of alumina trihydrate and an alkali metal aluminate; and a source of carbonate, such as sodium bicarbonate, are reacted under hydrothermal conditions at a temperature of between 160.degree.-200.degree. C. to produce synthetic hydrotalcite.

Method for the manufacture of hydrotalcite

A phosphate-containing synthetic hydrotalcite of the following empirical formula:
