Methods for chemical analysis of high purity indium oxide
Part 6. Determination of loss on ignition weighing method
1 Scope
This section GB/T 23364 specifies the method for determination of loss on ignition of high-purity indium oxide.
This section applies to the determination of loss on ignition of high-purity indium oxide, measurement range (mass fraction) of 0.05% to 1.00%.
2 Method summary
Sample was placed in a platinum crucible at a high temperature furnace is gradually heated up to 800 ℃, burning to constant calculated based on the loss on ignition which reduces quality.
3 Equipment
3.1 Analysis of balance. a sense of the amount of 0.1mg.
3.2 high-temperature furnace.
4 Sample
The specimen should be 105 ℃ ~ 110 ℃ drying 2h, placed in a desiccator to cool to room temperature.
Step 5 Analysis
5.1 Sample
Weigh 3.00g sample, accurate to 0.0001g.
5.2 Determination of the number of
Independently measured twice and averaged.
5.3 Determination
5.3.1 The sample (5.1) were plated at 800 ℃ constant burning and has a platinum crucible (including platinum cover) in.
5.3.2 platinum crucible placed in a high temperature furnace was slowly heated to 800 ℃, burning 1h.
5.3.3 Remove the platinum crucible, coolish. The platinum crucible placed in a desiccator, cooled to room temperature and weigh.
5.3.4 platinum crucible placed in a high temperature furnace again, burning at 800 ℃ 30min. 5.3.3 according to the following operation until the constant.
Calculation results of the analysis of 6
Ignition loss mass fraction w1 and its value is expressed in%, according to formula (1).
W1 m1 = m1 2 m1 0 × 1-
100 (1)
Where.
M1 --- before burning sample and a platinum crucible (including platinum cover) mass in grams (g);
M1 2 --- after burning a sample and a platinum crucible (including platinum cover) mass in grams (g);
0 --- mass m1 of 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
