GB/T 14505 method for chemical analysis of rocks and ores General rules and regulations
Principle 3
Sample after 105 ℃ drying to constant weight to lose mass is adsorbed water content.
4 instruments and equipment
4.1 Balance. three, a sense of the amount of 0.1mg.
4.2 cylindrical weighing bottle (diameter 35mm).
5 Sample
According to GB/T 14505 requirements, the maximum particle size of the sample should be less than 74μm.
Step 6 Analysis
6.1 Determination of the number of
The same sample, the general should be measured in duplicate, or by a certain percentage were measured in duplicate.
6.2 Sample volume
Weigh 1g sample to the nearest 0.1mg.
6.3 Determination
A sample (6.2) placed in 105 ℃ dried to constant weight and said weighing bottle (4.2) inside, gently shaking to make sample (6.2) evenly on the tile
Bottom half-open bottle in a dry 2h inner warmed to 105 ℃ ~ 110 ℃ oven. Remove, reclosable bottle, coolish into the dryer
, Cooled to room temperature, weighed (weighed before inching cap, so the bottle pressure and atmospheric pressure balance). And then placed in an oven and dried at the same temperature
Half an hour, remove the cooled and weighed until constant weight.
Note. can also be used instead of a platinum crucible lid weighing bottle.
