The oxide formed on NbSi2 at 1023 K consists of Nb2O5 and minor SiO2. The Nb2O5 is lose and nonprotective, which spalls from the sample during oxidation. The oxidation kinetics of all the NbSi2 samples at 1023 K follows a linear law. The oxidation rate is intrinsically determined by the reaction rate between the matrix and the oxygen in air, which in turn is determined by the exposure area of the sample.
无论是单晶还是多晶样品，氧化产物均为 Nb2O5和SiO2，生成的Nb2O5易剥落，样品的氧化动力学曲线均呈直线规律，证明NbSi2的氧化过程是一种本征无保护条件下氧元素与基体元素直接反应的过程。
