Blasch materials like our Oxytron , Nitron , Fused Silica and Alumina materials exceed in these high thermal shock appliions while also providing great non-wetting properties. Using our Blasch process for ceramic production, we produce products that provide the high tolerances and dimensional repeatability required in continuous casting operations to reduce downtime on your line.
Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded.
Technical ceramics temperature resistant materials - alumina, Mullite, Silicon Carbide, Zirconia, Quartz, also rare earth materials e.g Yttrium Oxide Covid-19: Anderman Industrial Ceramics Is Open For Business In these uncertain times around the world we are
The microhardness–nanostructure correlation of a series of silica/silicon oxycarbide porous composites has been investigated, as a function of pyrolysis temperature, T p. The pyrolyzed products have been studied by means of scanning electron microscopy, mercury porosimetry, chemical analysis, solid‐state 29 Si‐NMR, X‐ray diffraction, Raman spectroscopy, and microindentation hardness.
Silicon carbide features a high degree of hardness in addition to the above. At Iwatani, for many years we have been providing silicon carbide and silica fume, which can be used as raw materials of industrial ceramics and refractory materials. We also deal in
