Manufacturing Quality Control of Zinc sulfide
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Zinc Sulfide Content (ZnS) | Chemical Titration (e.g., EDTA Complexometric Titration) | The sample is dissolved in acid, pH adjusted, and then titrated with a standard EDTA solution to determine Zn²⁺ concentration. The ZnS purity is calculated indirectly from the zinc content. |
| Impurity Element Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | The sample is dissolved and nebulized into a high-temperature plasma. The characteristic emission lines of elements are used to quantify various impurities such as Fe, Pb, Cu, etc. |
| Sulfur Content | High-Frequency Infrared Absorption Method | The sample is combusted in a high-frequency furnace, and the released SO₂ gas is measured by an infrared detector to determine sulfur content, verifying the ZnS stoichiometry. |
| Moisture Content | Karl Fischer Titration | Measures water content (including crystalline or adsorbed water) based on the quantitative reaction of iodine and sulfur dioxide with water in a methanol-pyridine system. |
| Volatile Matter | Gravimetric Method (Thermogravimetric Analysis, TGA) | The sample is heated to a specified temperature, and the mass loss before and after heating is measured to assess the content of volatile substances. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Uses the principle of laser light scattering; particle size and distribution are calculated from the angular and intensity distribution of scattered light. |
| Specific Surface Area | BET Nitrogen Adsorption Method | Determines specific surface area by analyzing nitrogen adsorption isotherms at low temperature and applying the BET equation. |
| Crystal Structure | X-Ray Diffraction (XRD) | Analyzes X-ray diffraction patterns to identify whether the sample has sphalerite (cubic) or wurtzite (hexagonal) structure, and evaluates crystallinity. |
| Appearance and Color | Visual Inspection or Colorimeter | Assesses color, clumping, or foreign particles visually; a colorimeter provides quantitative color differences for batch consistency control. |
| Heavy Metal Limits | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After dissolving the sample, measures trace levels of toxic heavy metals such as Pb, Cd, Hg, and As to ensure compliance with environmental or application standards. |
