The determination of residue on ignition

   First the Griddle was burning 30 minutes at 600 ± 50 ℃, cooled and then weighed on a silica gel drier.Taking 1g sample was placed in a crucible and weighed, with 2ml sulfuric acid (5.5ml98% sulfuric acid diluted to 100ml) wetting the sample which was slowly heated until the sample completely low zoom.Cooling,using 2ml sulfuric acid (5.5ml98% sulfuric acid diluted to 100ml) to wet the sample, which was slowly heated until no white smoke, and then placed at 600 ±50℃ calcined to obtain the residue, to ensure that the entire process does not  produce white smoke.Cooling Griddle silica gel dryer and then weighed to calculate the mass of the residue.

The determination of Loss on drying

  Weigh a sample of approximately 2g (weighing accuracy 0.0001g),Record the weight of m,The sample was placed in a Petri dish constant weight (weight recorded as m0), the tile, the thickness of not more than 5mm, into the oven (As next dish cover removed) drying at 105-110 ℃ 3 hours.When removing, make sure the dish cover,be placed in a desiccator to cool, then weighed and the weight (including surface dish) m1.

Loss on drying in accordance with the following formula:

Where:

         m-- sample, g

       m0-- dish, g

          m1-- After drying the quality of the sample and the dish, g
