Abstract
This invention provides substantially spherical, micron and submicron sized alkali metal bicarbonate particles. When combined with a liquid medium, the alkali metal bicarbonate particles have an exceptional capability to form a flowable slurry which demonstrates long term stability.
Claims25
Substantially spherical alkali metal bicarbonate particles having a median particle size of from about 0.2 up to less than 1.0 μm and a surface area of from about 120 to about 140 cm3/g.
A slurry comprising substantially spherical, micron-sized and/or submicron sized alkali metal bicarbonate particles, said particles having a median particle size of from about 0.2 to about 50.0 μm and a surface area of from about 120 to about 140CM3/g, dispersed in a liquid medium, wherein the slurry has a loose bulk density of about 1.40 to about 1.60 grams per mL and a Zeta potential of about 2 to about 11 mV.
