Refractory bed materials for AFBC and CFBC boiler duty.

The bed material page now presents the technical specification in a cleaner format, with visual cues for AFBC and CFBC boiler usage instead of a rigid legacy layout.

Chemical properties covering alumina, silica, alkalis and iron limits.

Particle size guidance for AFBC and CFBC boiler applications.

Bulk density and physical property data retained from the original page.
