| Abstract: | A method of determining total boron in zirconium-boron ceramics was studied. The samples were decomposed by sulphuric acid, ammonium sulfate, and potassium bichromate solutions. Under the conditions such as nitraogen carrying distillation with flow rate of 150 mL/min, water bath beating and NaOH adsorption (solution), boron was distiled as methyl borate and separated by cation-exchange chromatography. The total (boron) was determined by inductively coupled plasma atomic emission spectrometry. The relative standard (deviation) of method (n=6) is less than 2.0%, and the recovery is 99%. |
