Boria Effects on the High Temperature Oxidation of …

CMCs are comprised of silicon carbide (SiC) fibers coated with a boron nitride layer eedded in a SiC matrix. SiC and boron nitride will react with oxygen upon exposure to the engine’s high temperature oxidizing environment, forming silica and boria oxidation products, respectively, which together form a borosilie glass.

Carbure de silicium — Wikipédia

Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique réfractaire ultradure semiconductrice synthétique, qu''on peut trouver dans la nature sous la forme d''un minéral très rare, la moissanite.Grâce au procédé Acheson, depuis la fin du XIX e siècle, on sait produire industriellement de la poudre de carbure de silicium, qui servit d''abord comme abrasif.

Purcell Enhancement of a Single Silicon Carbide Color …

Silicon carbide has recently been developed as a platform for optically addressable spin defects. In particular, the neutral divacancy in the 4H polytype displays an optically addressable spin-1 ground state and near-infrared optical emission. Here, we present the Purcell enhancement of a single neutral divacancy coupled to a photonic crystal cavity. We utilize a coination of
