As a new type tool material, the excellent capabilities of silicon nitride ceramics cutting tools ravel out many cutting problems of super hard materials.

The dielectric property of silicon nitride ceramics was measured at 10.

Silicon nitride ceramics is a sort of material of high temperature and high intensity structure which have been developed since 1950s.

However,it is difficult to make silicon nitride ceramic parts.

In the paper, the dispersion of nano-Si3N4 powder, the influence of different nano-Si3N4 concentration on silicon nitride mechanical properties, the influence of the different nano-Si3N4 concentration on silicon nitride ceramic using properties, th.

In this paper, the influence of sintering technology on the microstructure and mechanical properties of the silicon nitride ceramic were studied.

Hard and wear-resistant titanium nitride coatings were deposited by pulsed high energy density plasma technique on silicon nitride ceramic cutting tools at ambient temperature.

The effect of holding time on intergranular phase and mechanical property of GPS silicon nitride ceramics was studied.

Bonding of Si 3N 4 ceramics was performed with Y 2O 3 Al 2O 3 SiO 2(YAS) X glass solders, which were mixed with TiO 2 (YT) and Si 3N 4(YN) respectively.

Si 3N 4 ceramics die was prepared by the method of reaction bond,and tests of drawing stainless steel (SUS304) with ceramics die lubricated with water base drawing lubricator have been carried out in YA-100 type drawing machine with four columns.
