Claim 7:
8. The method according to claim 1, wherein the crystalline free-plate habit has:
1) a powder X-ray diffraction pattern comprising peaks, in terms of 2θ, at 8.2°±0.2°, 16.4°±0.2°, 20.5°±0.2°, and 24.6°±0.2°;
2) a differential scanning calorimetry trace comprising an endotherm with an extrapolated onset temperature of 205.5° C. to t 208.5° C. at a scan rate of 10° C./minute;
3) a dynamic moisture sorption (DMS) profile with an adsorption phase from 30% RH to 90% RH wherein said crystalline free-plate habit gains about 0.3% weight or less at 90% RH; and/or
4) a BET specific surface area of about 0.6 m2/g to about 4.0 m2/g.
