The behaviour of a sintered and a reaction bonded silicon carbide has been investigated in aqueous HCl, HF, HNO 3, and H2SO 4, using standard immersion and new electrochemical methods. Both materials were passive in HCl, HNO 3 , and H 2 SO 4 because of the formation of a surface silica film, and were active in HF.

Silicon Nitride Ceramics - International Syalons
Silicon Nitride Ceramics Silicon nitrides (Si3N4) are a range of advanced engineering ceramics characterised by high strength, toughness and hardness and excellent chemical and thermal stability. Silicon nitride was discovered in the mid-nineteenth century but did not lend itself to ease of fabriion, due to its covalently bonded nature. This initially led to the development […]
