High-temperature strength
sic pipe can be found in industrial furnaces and kilns as component parts or thermocouple protectors. sic ceramics are extremely hard, ultra-tough synthetic material with a Mohs scale rating of 9. As the hardest ceramic, sic ceramics can withstand extreme temperatures – an advantage in industrial furnace environments – as well as having excellent mechanical strength, wear resistance, thermal shock resistance and mechanical shock resistance properties that make it suitable for applications including abrasion-resistant tubes/parts in power generation, corrosion-resistance components for chemical industries like papermaking or oil drilling and even electrical/automotive components.
This study involved subjecting sintered and CVD b-SiC samples to high pressure and temperature conditions in a diamond anvil cell, where an x-ray diffraction pattern was collected at each pressure and temperature point to assess mechanical response of material. Furthermore, surface strain measurements were taken using digital image correlation (DIC) method and acoustic emissions (AE). A 3D model was also created to estimate stress-strain distribution across the sample surface area.
Results indicate that a-SiC is more durable than other hard materials like diamond, moissanite and alfa silicon nitride, making it suitable for applications exposed to harsh environmental conditions. Unfortunately corrosion compromises its longevity through weakening its strength; corrosion increases surface flaws which diminish its overall strength over time.
