Amorphous boron nitride thin coatings (∼0.2 μm) have been formed on Nicalon and C‐Nicaion (pre‐carbon‐coated Nicalon) yarns via dip coating in boric acid solution followed by heating and nitriding in NH 3 gas at 1000°C. X‐ray photoelectron spectroscopy (XPS) and Auger electron spec‐troscopy (AES) studies have shown the formation of boron nitride.

Silicon carbide fiber/silicon carbide matrix (SiC-SiC) composites exhibit remarkable material properties, including high temperature strength and stability under irradiation. These qualities have made SiC-SiC composites extremely desirable for use in advanced nuclear reactor concepts, where higher operating temperatures and longer lives require performance improvements over conventional metal
Silicon carbide is an artificial mineral with a strong covalent bonding. It is superior to alumina and silicon nitride in hardness. And it is good in abrasion-resistance, especially in a stick-slip condition. It maintains mechanical strength at a high temperature. Besides, it is excellent in corrosion-resistance even to hot acid and alkaline

2018-10-8 · Silicon Carbide The utility of silicon oxide coatings is limited by its applicability for good barrier properties. There appears to be a fundamental limit to how effective SiO 2 thin films can be to water vapor transport9. Silicon carbide, in this case, has superior performance as a barrier to water vapor as compared to SiO 2. For example,
