穆斯堡尔谱技术已被用来识别玻璃系统Na 2 O·B2 O3·Fe 2 O3含有高达35重量%的Fe 2 O3的晶体形成。该系统中的玻璃表现出加宽的四极分裂双重峰，峰间距为1.0 mm/sec，半峰全宽为0.7 mm/sec，相对于Cr中的Fe的异构体位移为0.3-0.5 mm/sec。晶体材料的形成与样品组成和制备程序定性相关。穆斯堡尔谱技术识别少量晶体材料的灵敏度与X射线技术进行了比较。
Mossbauer techniques have been employed to identify crystal formation in the glass system Na2O·B2O3·Fe2O3 containing up to 35 wt% Fe2O3. Glasses in this system exhibit a broadened, quadrupole split doublet with a peak separation of 1.0 mm/sec, a full width at half‐maximum of 0.7 mm/sec, and an isomer shift of 0.3–0.5 mm/sec with respect to Fe in Cr. The formation of crystalline material is correlated qualitatively with sample composition and preparation procedure. The sensitivity of the Mossbauer technique for identification of small amounts of crystalline material is compared with that of x‐ray techniques.
