ABSTRACT:
Silicon nitride-based powder composition enabling materials of densities exceeding 3.10 g/cm.sup.3 to be obtained by pressureless hot sintering. This composition contains, intimately mixed by pulverisation, Si.sub.3 N.sub.4 having a particle size not exceeding 1 .mu.m and up to 6% by weight of a densification aid comprising very finely ground magnesium oxide and aluminium oxide. This composition enables mechanical parts to be economically manufactured by moulding followed by sintering, their properties being practically equivalent to those of parts obtained by machining hot pressed blocks of Si.sub.3 N.sub.4.
