The particles deposited on the support material have a degree of, crystallinity, determined by X-ray diffraction of more than 2 and an average , particle size between 2 and 10 mm.

Why it's free to use
- Filed May 2, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 2, 2022.
