Mullite-mullite environmental barrier coatings on silicon nitride by composite sol-gel

Silicon nitride is susceptible to paralinear oxidation in applications exposed to combustion environments, such as glow plugs in direct injection natural gas engines. The oxide layer may become volatile in moist high-temperature environments. To protect Si₃N₄, environmental barrier coatings (EBC)...
