1 Scope

This section YS/T 861 provides for aluminum, nickel, silicon, iron, chromium, copper, tantalum content determination of niobium titanium alloy. This section applies to the determination of niobium-titanium alloy of aluminum, nickel, silicon, iron, chromium, copper, tantalum content, the measurement range shown in Table 1. Table 1 Element measurement range /% Al 0.0030 ~ 0.020 Ni 0.0030 ~ 0.020 Si 0.0050 ~ 0.020 Fe 0.0050 ~ 0.020 Cr 0.0030 ~ 0.020 Cu 0.0030 ~ 0.020 Ta 0.010 ~ 0.40

2 Method summary

Sample decomposition with hydrofluoric acid and nitric acid. Solution directly to the argon plasma excitation source, subjected to spectral measurement, calculated from the measured elements content.

3 Reagents

Unless otherwise indicated, this part of the reagents are excellent pure reagent, which is a water or equivalent purity water. 3.1 Hydrofluoric acid (ρ = 1.14g/mL). 3.2 nitric acid (ρ = 1.42g/mL). 3.3 hydrochloride (11). 3.4 nitric acid (11). 3.5 Hydrofluoric acid (11). Argon 3.6 volume fraction ≥99.995%. 3.7 highly pure titanium, the measured element content < 0.001%. 3.8 high-purity niobium or niobium hydroxide, the measured element content < 0.001%. 3.9 standard aluminum stock solution. Weigh 1.0000g of aluminum (wAl≥99.99%), placed in 250mL beaker covered with a watch glass, add 100mL of hydrochloric acid (3.3), a low temperature to dissolve. Until completely dissolved and then cooled and transferred to 1000mL volumetric flask, dilute with water to volume, and mix. ...
