1 Scope
This section YS/T 1028 specifies the method for determination of lithium iron phosphate in the amount of carbon.
This section applies to the determination of lithium iron phosphate in the carbon content. Measuring range: 0.5% to 5.0%.
2 Method summary
The sample was placed in a porcelain crucible and a flux, the oxygen flow by heating in a high frequency induction furnace, carbon dioxide generated by the combustion, the carrier of oxygen to
Infrared absorption cell. Changes in carbon dioxide concentration on the infrared absorption of energy followed Beer's law. Analysis of the results of the carbon content by a display in hundreds
CONTENT displayed directly.
3 Reagents and materials
3.1 Oxygen: not less than 99.5% purity.
3.2 Desiccant: Anhydrous magnesium perchlorate, size 0.7mm ~ 1.2mm.
3.3 cleaning agent: caustic soda asbestos, particle size 0.7mm ~ 1.2mm.
Iron 3.4: purity greater than 99.8%, carbon content less than 0.002%.
3.5 tungsten particles: carbon content of less than 0.002%.
3.6 porcelain crucible: before the porcelain crucible placed in a muffle furnace and calcined at 1200 deg.] C of not less than 2h, after removing coolish stored in a desiccator.
4 Instrument
The instrument parameters shall meet the following requirements:
--- High-frequency induction furnace: melting temperature of the sample should meet the requirements.
--- Electronic balance: a sense of the amount of 0.1mg.
5 Sample
5.1 sample before use should be placed in an oven of 110 ℃ ± 5 ℃ drying 1h, after removing stored in a desiccator.
5.2 Sample size should be less than 0.10mm.
Step 6 Analysis
Warning --- the hazards associated with the combustion analysis mainly calcined porcelain crucible and melting process of combustion. Any time Crucible
Pliers, and used crucibles stored in a suitable container. Using oxygen cylinders shall comply with the general safety measures. Local oxygen enrichment can cause
