1 Scope

GB/T 18114 provisions of this part of the determination of rare earth concentrates moisture. This section applies to the determination of rare earth concentrates in moisture measurement range. 0.02% to 20.00%.

2 principle of the method

Weigh a certain amount of rare earth concentrate sample, dried at 105 ℃ ~ 110 ℃ certain period of time, said its loss of quality, calculate the amount of water.

3 instruments and reagents

3.1 Oven. temperature greater than 110 ℃. 3.2 weighing bottle. 3.3 Balance. a sense of the amount of 0.0001g.

4 Sample

Rare earth concentrate sample sealed. Step 5 Analysis 5.1 Sample Weigh 10g ~ 20g sample (4), accurate to 0.0001g. 5.2 Determination of the number of Weigh two samples (5.1) parallel determination of the mean value. 5.3 Determination A sample (5.1) into constant weight weighing bottle (3.2), and placed 105 ℃ ~ 110 ℃ oven bake 2h, remove, add dried coolish Dryer, cooled to room temperature, weighed, and repeat this operation until constant weight.

6 Calculation and presentation of analysis results

According to equation (1) calculate the water content (%). w (H2O) = m1-m2m × 100 (1) Where. Mass m1 --- weighing bottle and sample before drying, in units of grams (g); Mass m2 --- dried sample and weighing bottle in grams (g); M --- the quality of the sample, in grams (g).

7 precision

7.1 Repeatability Found two independent test results obtained under repeatability conditions within the average range given below, these two test results The absolute difference does not exceed the repeatability limit (r), exceeds the repeatability limit (r) does not exceed 5% repeatability limit (r) by the data in Table 1 using a linear Obtained by interpolation. ......
