1 Scope

GB/T 4324 This section specifies the method for determination of loss on ignition of tungsten trioxide. This section applies to the determination of tungsten trioxide in the loss of ignition. Measurement range of 0.05% to 1.00%.

2 Method summary

Tungsten trioxide at 780 ℃ ~ 800 ℃ burning, wherein water, salt and volatile substances to escape, the loss in mass for the ignition loss. Step 3 Analysis 3.1 Sample Weigh 2.00g sample, accurate to 0.0001g. 3.2 Determination of the number of Independently measured twice and averaged. 3.3 Determination 3.3.1 The porcelain crucible placed 780 ℃ ~ 800 ℃ high temperature furnace burning 1h, after removing coolish cool to room temperature in desiccator, weigh. again The porcelain crucible placed 780 ℃ ~ 800 ℃ high temperature furnace burning 0.5h, after removing coolish placed in a desiccator to cool to room temperature (cooling time should be The previous agreement), weighing. Repeat until constant weight. 3.3.2 The sample (3.1) into constant weight porcelain crucible, placed 780 ℃ ~ 800 ℃ high temperature furnace burning 2h, after removing the cooling set Dryer cooled to room temperature (cooling time should be consistent with an empty crucible cooling time), weighed. Then porcelain crucible at 780 ℃ ~ 800 ℃ high temperature furnace The burning 0.5h, removed after cooling placed in a desiccator cooled to room temperature (cooling time should be consistent with an empty crucible cooling time), weighed. Repeat this Operating until constant weight. Calculation results of the analysis of 4 Ignition loss amount w ignition loss amount, expressed in%, according to equation (1). w = loss on ignition m1-m2 m × 100 (1) Where. m --- Sample volume in units of grams (g); m1 --- burning in front of the sample with constant weight porcelain crucible mass in grams (g); M2 --- After burning the sample with a porcelain crucible mass in grams (g). ......
