1 Scope

This part of YS/T 281 specifies the determination of oxygen content in cobalt. This part applies to the determination of oxygen in cobalt. Measuring range. 0.2% ~ 1%.

2 principle of the method

The preformed sample was put into a high temperature degassed graphite crucible, heated in an argon (or helium) gas stream, and the oxygen in the sample The CO is oxidized to CO2 by the precipitation of CO or with argon (or helium) through a rare earth oxidized copper furnace at 400 ° C and introduced into an infrared detector Determination, the computer automatically gives oxygen content.

3 reagents and materials

3.1 argon (or helium). (wAr/He ≥ 99.99%). 3.2 dynamic gas (nitrogen or compressed air). purity of about 99.8%. 3.3 Carbon tetrachloride. 3.4 Rare earth copper oxide. 3.5 anhydrous magnesium perchlorate. 3.6 Asbestos. 3.7 glass wool. 3.8 Vacuum grease. 3.9 graphite crucible. the crucible before use into the oven at 110 ℃ ± 5 ℃ baking 1h, then transferred to the dryer to cool to room temperature. 3.10 Nickel Foil. (wO < 0.0020%), scrub the surface of the nickel foil with a clean dyed carbon tetrachloride, cut into small pieces and put it into carbon tetrachloride Soak for about 15min; use, with a hair dryer to dry, so that attached to the nickel foil surface of carbon tetrachloride completely volatile. 3.11 Oxygen Standard Samples. Use standard samples similar to the oxygen content of the substance to be measured. It is best to use a standard sample of cobalt in cobalt.

4 instruments

Pulse heating infrared absorber. with electronic AC voltage regulator. The instrument should meet the following criteria, the use of working conditions to ensure that the oxygen in the sample completely released. --- Instrument sensitivity ≤ 0.0010%; --- pulse heating power of not less than 6.5kW (furnace temperature of not less than 2400 ℃); --- system blank ≤ 0.0010%. ......
