Abstract
A novel material can be obtained by chemical reaction from elemental or alloyed silicon powder, to which fillers are optionally added. The novel material, which can be worked mechanically, can be further refined by means of subsequent heat treatment and/or surface coating, and can in many cases be used instead of polycrystalline or sintered silicon.
