Study Notes
Chemical Analysis in Metallurgy
- Chemical analysis in metallurgy involves determining the composition of raw materials, products, and by-products.
- Two types of analysis exist: qualitative and quantitative.
- Qualitative analysis identifies the elements or ions present in a substance. It doesn't measure the amount, only presence or absence.
- Quantitative analysis determines the quantity or number of elements or compounds present.
- Qualitative analysis is crucial even if the presence of an element is known. It helps select the right quantitative method.
Qualitative Analysis Methods
- Qualitative analysis in metallurgy uses standard analytical chemistry techniques to identify elements/ions (cations/anions) in raw materials and products.
- These techniques involve transforming the target element/ion into a compound with unique characteristics.
- Visual cues like color changes or precipitate formation help pinpoint the presence of specific elements and compounds.
- The technique used depends on the material being analyzed.
Qualitative Analysis of Inorganic Compounds
- For inorganic compounds, qualitative analysis often involves identifying the ions present.
- Ionic compounds are identified based on their chemical properties. Covalent compounds are identified via physical properties like boiling point and refractive index.
Materials Analyzed in Metallurgy
- Chemical analysis is needed for raw materials, ores, metals, alloys, fluxes, slags, and by-products.
