Abstract
Boron compounds such as alkali metal or alkaline earth metal borates capable of forming hydrates or higher hydrates may be formed into shaped bodies by forming into a paste with water and allowing the water to be bound to form a solid shaped body. The bodies are useful as inserts into preformed cavities in structures, e.g. of wood, liable to insect, fungal or other infestation by virtue of the slow dissolution of the insert and the toxicity to such organisms of the boron compounds.
Claims10
A process for the production of a shaped body, comprising one or more boron compounds, suitable for use as a preservative insert in structures liable to biological attack, characterised by forming a paste comprising water and one or more boron compounds capable of binding water by hydration, shaping the paste and allowing the shaped paste to solidify by the binding of at least a portion of the water therein to form the shaped body.
A shaped body suitable for use as a preservative insert in structures liable to biological attack comprising particles of one or more boron compounds bound by crystallisation.
