1 Scope
YS/T 1075 This section provides the vanadium aluminum, aluminum master alloys determination of molybdenum in the amount of oxygen.
This section applies to vanadium aluminum, aluminum master alloys determination of molybdenum in the amount of oxygen. Measurement range. 0.010% to 0.30%.
2 Method summary
In an inert atmosphere, is heated to a molten sample pulses, i.e. pulses containing sample melted in the furnace graphite crucible. Samples of different forms
Oxygen at high temperatures to generate a large number of small amounts of CO and CO2 with the graphite crucible, which along with the heat carrier gas flow rare earth copper oxide, so that
Conversion of CO to CO2. Then, the mixed gas stream into the cell infrared detector, the oxygen content of the sample was measured.
3 Reagents
3.1 Carrier gas. argon or helium (volume fraction ≥99.99%).
3.2 Power gas. oil-free compressed air.
3.3 Nickel bag (thickness ≤0.05mm, wO≤0.001%).
3.4 sets graphite crucible.
3.5 standard sample.
4 Instrument
The inert gas fusion - thermal conductivity/IR detection system (including one electrode furnace, purification and analysis of a carrier gas stream conversion systems, carbon monoxide red
External infrared detectors and carbon dioxide detectors, computers and software control system).
Recommended Instruments working conditions are as follows.
Minimum analysis time. 40s; exhaust Power. 6000W; analysis of power. 5000W.
5 Sample
The specimen shall crush a particle size less than 500μm. If oil is required with an organic reagent acetone, dry before testing.
Step 6 Analysis
6.1 Sample
Weigh 0.040g ~ 0.070g sample (Chapter 5), accurate to 0.0001g.
