Claims24
A composition, comprising at least 50% w/w activated vaterite and between 0.1-0.6 wt % stabilizer wherein the stabilizer comprises the stabilizer incorporated in crystal lattice of the activated vaterite and wherein the stabilizer is sulfate.
A method for making a composition, comprising:
- contacting CO2 from a CO2 source with a solution comprising proton removing agent, alkaline earth-metal ions and a stabilizer to make a composition comprising at least 50% w/w activated vaterite and between 0.1-0.6 wt % stabilizer wherein the stabilizer comprises the stabilizer incorporated in crystal lattice of the activated vaterite in the composition and wherein the stabilizer is sulfate.
A composition formed by a method, comprising contacting CO2 from a CO2 source with a solution comprising proton removing agent, alkaline earth-metal ions and a stabilizer to make a composition comprising at least 50% w/w activated vaterite and between 0.1-0.6 wt % stabilizer wherein the stabilizer comprises the stabilizer incorporated in crystal lattice of the activated vaterite and wherein the stabilizer is sulfate.
