1 Scope
GB/T 16484 This part specifies the determination of the light rare earth carbonate loss on ignition.
This section applies to the determination of light rare earth carbonate ignition loss, the measurement range of 40.00% ~ 90.00%.
Principle 2
The sample was 950 °C burning, burning before using the sample and calculate the loss on ignition ignited mass difference.
3 Equipment
3.1 Analysis of balance
a sense of the amount of 0.1mg.
3.2 high-temperature furnace
1000 °C.
3.3
a platinum crucible.
4 Sample
Weighing the sample immediately after the opening.
Step 5 Analysis
5.1 Sample
Table 1 sample was weighed, accurate to 0.0001g.
Table 1
Sample Sample volume/g
The dried sample relatively 3
Relatively moist sample 50 5.2 Determination of the number of
Weigh two samples were measured parallel to the mean value.
5.3 Determination
The sample (5.1) in a burned at 950 °C to constant weight in a platinum crucible, calcined at 950 °C 1h. The platinum crucible out, coolish, set
In the dryer to cool to room temperature. Call quality on an analytical balance, repeat the operation until the difference between two adjacent mass does not exceed 1mg.
6 Calculation and presentation of analysis results
According to equation (1) calculate the loss on ignition of the mass fraction (%).
W1 (loss on ignition) 1- m1 = m1 2 m1 × 100 (1)
Where.
M1 --- before burning a platinum crucible and sample mass, in grams (g);
