According to the X-ray diffraction pattern of the ZC20 sample, besides the reflections from cubic ZrC and tetragonal MoSi 2, traces of β-silicon carbide were detected (Figure 2). Considering the wide range of stability of fcc transition metals carbides MC x , X-ray diffraction at high angles was performed with a Si standard in order to detect any s shift.

Tungsten carbide is approximately two times stiffer than steel, with a Young''s modulus of approximately 550 GPa, and is much denser than steel or titanium. It is comparable with corundum (α-Al 2 O 3 ) or sapphire/ruby in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitrideand diamond, in the form of powder, wheels, and compounds.
Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.

Silicon carbide (SiC) was sintered using two different additives: AlN-Y2O3 or AlN-CRE2O3. CRE2O3 is a mixed oxide formed by Y2O3 and rare-earth oxides. The crystalline structures of the phases were analyzed by high-resolution X-ray diffraction using synchrotron light source.
Silicon carbide can be sintered up to high densities by means of liquid phase sintering under low gas pressure with AlN-Y 2 O 3, AlN-Yb 2 O 3, and AlN-La 2 O 3 sintering additives. As-sintered materials exhibited fine-grained homogeneous microstructure.

However, boron carbide is very brittle and undergoes softening past the critical HEL point, unlike similar ceramics such as silicon carbide . This loss of strength limits the material’s performance in critical appliions. The sudden failure of boron carbide under
Porous sintered silicon carbide samples were made using different proportions of grit sizes and various firing schedules. Both resistivity and crushing strength were determined. It was found that the resistivity is dependent upon degree of sintering (indied by crushing …
A seal code is an abbreviated method of communiing basic specifiions for the mechanical seal. Sadly, the seal code has been changed with every edition of API 682. Fortunately, the new code, described in API 682 4 th Edition Annex D, is the best to date and includes some concepts and codes from the historical API 610 seal code.
