1 Scope

GB/T 13747 provisions of this part of zirconium and zirconium alloys Determination of hafnium content. This section applies to sponge zirconium, zirconium and zirconium alloy determination of hafnium content. Measurement range. 0.0050% ~ 5.00%.

2 method summary

Hydrochloric acid and hydrofluoric acid dissolved sample, dropping nitric acid oxidation. Inductively Coupled Plasma Atomic Emission Spectrometry was used for the determination, according to the work Calculated by the curve of hafnium mass concentration, expressed in mass fraction measurement results.

3 reagent

Unless otherwise stated, only reagents identified as analytical grade and laboratory grade II water were used in the analysis. 3.1 Nitric acid (p = 1.42 g/mL). 3.2 Hydrochloric acid (1 1). Hydrofluoric acid (1 1). 3.4 Metal zirconium (wZr ≧ 99.95%, wHf < 0.0005%). 3.5 Hafnium standard stock solution Weigh 1.0000g of pure hafnium (wHf ≥ 99.95%) in a Teflon beaker, slowly dropwise add 4mL of hydrofluoric Acid (3.3) to dissolve, add 10mL hydrochloric acid (3.2), shake. Remove, cool to room temperature, transferred to 1000mL volumetric flask, diluted with water To the mark, mix well. Immediately transferred to a plastic bottle to save. This solution 1 mL contains 1.0 mg of hafnium. 3.6 hafnium standard solution Pipette 50.00mL hafnium standard stock solution (3.5) in 500mL volumetric flask, add 2mL hydrofluoric acid (3.3), 5mL hydrochloric acid (3.2) diluted with water to the mark, mix well. Immediately transferred to a plastic bottle to save. 1 mL of this solution contains 100 μg of hafnium. 3.7 Argon. Volume fraction ≥ 99.99%.

4 instruments

Inductively Coupled Plasma Atomic Emission Spectrometer with hydrofluoric acid atomizer system.

5 sample

5.1 Sampling Sponge zirconium, zirconium and zirconium alloy sampling should have been promulgated by the corresponding standard methods. 5.2 Sample Processing Cut the specimen to a length of not more than 5 mm of debris. ......
