Reaction bonded silicon nitride RBSN

The tensile fracture strengths of three different structural ceramics are listed below hot-pressed silicon nitride (HPSN), reaction-bonded silicon nitride (RBSN), and chemical vapor-deposited silicon carbide (CVDSC), measured at room temperature. [Pg.396]

Material type Reaction bonded silicon nitride (RBSN) Sintered RBSN (SRBSN) Sintered silicon nitride (SSN) Gas pressure sintered silicon nitride (GPSN) Hot-pressed silicon nitride (HPSN) Sinter HIP silicon nitride (Sinter-HIPSN) HIP-ed silicon nitride HIP-SN... [Pg.752]

The ceramic materials investigated in this paper are hot-pressed silicon nitride (HPSN), reaction-bonded silicon nitride (RBSN), zirconia-toughened alumina (AI2O3), and porous SiC. The available material properties for these ceramics are given in Table 4.3. The HPSN and zirconia-toughened alumina ceramics were in the shape of flexural strength test bars cut from billets. The RBSN ceramic was molded into bars of the shape of flexural test specimens. The porous SiC ceramic was provided in the shape of flexural test specimens. [Pg.90]

The last two examples are the synthesis of reaction-bonded silicon nitride (RBSN) and reaction-bonded titanium nitride (RBTN). Ti(N) is titanium with dissolved nitrogen. [Pg.169]

Silicon powder is compacted to a density of 60% of the theoretical value and heated in N2 to form reaction bonded silicon nitride (RBSN). If the reaction goes to completion and there is no change in the external dimensions of the compact, determine the porosity of the RBSN. [Pg.44]

The strong deterioration of the strength of HT superalloys with temperature is given for comparison.

Alternatively, Si3N4 can be manufactured as reaction bonded silicon nitride (rbsn). This process starts with silicon powder that reacts with nitrogen in a nitrogen atmosphere. This produces a somewhat porous ceramic, containing both a and (3 phase. The strength of this material is much smaller than that of sintered silicon nitride due to the different grains and the larger defect size caused by the increased porosity (see table 7.4). [Pg.250]

More common today is Reaction Bonded Silicon Nitride (RBSN). Silicon powder is pressed, extruded or cast into shape then carefully nitrided in a Nj atmosphere at 1100-1400°C, so as to prevent an exothermic reaction that might melt the pure silicon. [Pg.787]
