Abstract
Shaped articles of silicon nitride are produced by mixing powdered silicon with a binder comprising sugar and water, the binder being of sufficient strength to hold the powder together to enable it to be moulded or extruded to shape and, after moulding or extrusion, converting the silicon to silicon nitride, e.g. by heating in an atmosphere of nitrogen. After moulding or extrusion, but before conversion to silicon nitride, the binder may be wholly or entirely dried out, allowing the articles to be machined. The sugar and water are preferably used in equal proportions and the proportion of binder in the silicon may be in the range 2% to 30% by weight.
