The authors have derived an x-ray method of determining Ta/sub 2/O/sub 5/, TiO/sub 2/, Fe/sub 2/O/sub 3/, Nb/sub 2/O/sub 5/, C1 and SiO2 with a KRF-18 quantometer. The method should provide accuracy in determining these elements characterized by relative derivations. The main components of niobium hydroxide were ground for improved determination. The method allows one to analyze a sample in 30 min. In a six hour working day, an assistant can analyze up to 25 samples. The time required for one sample in the chemical method is about 30 hours.
