## Abstract Well‐sized spherical beads of phenolic resin (0.3–1.2 mm) with an extremely high compressive strength (>8 kg/1.0 mm bead) and hardness (>98%) were synthesized via suspension polymerization of phenol and formaldehyde. Barium hydroxide was used as a catalyst (1.68–10.13 wt %) to get large
