Hydroxyapatite lathlike monocrystalline particles were prepared using high‐energy dispersing equipment in combination with a pH shock‐wave method. The Ca/P atomic ratios were very close to theoretical, and the acidic group content was very small. The particles were nonporous, with anisotropic crystal growth and average grain size ∼140–1300 nm in length, ∼20–100 nm in width, and ∼10–40 nm in thickness. The high‐speed dispersing equipment created the proper hydrodynamic conditions for lathlike particle growth in the [001] direction. The hydroxyapatite particles formed aggregates of 1–5 μm average diameter.
