XB/T 611-2009 Chemical analysis method of rare earth oxalate Determination of ignition loss by gravimetric method

1 scope

This standard specifies the determination method for the ignition loss of rare earth oxalate This standard applies to the determination of the ignition loss of rare earth oxalate. Measuring range. 55.0% to 75.0%

2 Principles of the method

The difference in mass of the sample before and after ignition at 950°C is the ignition loss.

3 Apparatus

3.1 High temperature furnace. temperature >1000℃ 3.2 Platinum dishes.

4 samples

Weigh the sample immediately after unsealing.

5 Analysis steps

5.1 Sample Weigh about 20g sample (4), accurate to 0.0001g. 5.2 Determination of quantity Weigh two samples for parallel determination, and take the average value. 5.3 Determination Place the sample (5.1) in a platinum dish (3.2) that has been burned to a constant weight at 950°C, and burn it in a high-temperature furnace (3.1) at 300°C for 0.5 h. Raise to 950°C and burn for 1 hour, cool slightly, place in a desiccator, cool to room temperature, weigh the mass on an analytical balance, and repeat the operation until the platinum dish Together with the quality of the fired material is constant.

6 Calculation and expression of analysis results

Calculate the mass fraction (%) of ignition loss according to formula (1). (1) Where.

7 Precision

7.1 Repeatability The measured value of two independent test results obtained under repeatability conditions, within the range of the average value given below, the two test results Obtained by interpolation. XB/T 611-2009
