Compressed glassy carbon: An ultrastrong and elastic …

For example, cemented tungsten carbide has an extreme compressive strength up to 9 GPa, but its heavy weight leads to excessive energy consumption. Light-element compounds, such as silicon carbide and boron carbide, are low-density and high-strength and are thus preferred materials for military armor and aerospace shields to protect certain vital equipment.

:: RDE :: Restorative Dentistry & Endodontics

According to Matinlinna et al. [], the silica content on the Y-TZP bonding surface after tribochemical silica coating is too low to achieve sufficient silanization. Moreover, siloxane bonds may be sensitive to hydrolytic degradation in conditions involving contact with moisture, such as water storage and thermocycling, thus affecting the long-term stability of the adhesive interface [ 16 , 30 ].

Abstract: A novel technique was developed to synthesize porous silica–matrix ceramics from silicon carbide and alumina with an Y2O3 addition, using pine sawdust as a pore former. The porous ceramics were fabried at temperatures of 1300–1500 oC in air by a reaction–bonding process based on two reactions: (1)SiC+2O2→SiO2+CO2 (Oxidation) and (2)2SiO2+3Al2O3→3Al2O3·2SiO2 (Mullitization).
