The influence of TiN, Mo, Ni additions on resistivity and strength of hot pressed silicon nitride
has been investigated. Dense material based on silicon nitride with additives up to 30 % TiN
and 1,7 % Mo (volume percents) was prepared. It has bending strength 450–500 MPa and specific
resistivity~ 10-2 Ω·m. The behavior of material permits to manufacture of complex shape parts by
spark cutting. The nickel addition has negative affect on strength of hot pressed silicon nitride.
