Abstract
A bed of particulate solids including some hydrated materials can be converted by controlled irradiation with subinfrared electromagnetic radiation into a unitary porous solid that is mechanically strong enough for easy handling. When the particulate solids include typical mildly acid to alkaline cleaner materials, a block or tablet especially suitable for automatic cleaning machinery, with a very fast dissolution rate in water, can readily be obtained.
