Industrial Applications of Calcium metasilicate
| Industry | Application | Process |
|---|---|---|
| Construction Materials | Cement and concrete additives | Incorporated into cement clinker to enhance early strength and durability |
| Refractories | Raw material for high-temperature refractory products | Sintered with other oxides to produce refractory bricks or castables |
| Ceramics Industry | Flux in glazes and ceramic bodies | Mixed with quartz, feldspar, and other raw materials for high-temperature firing of ceramic products |
| Environmental Engineering | Stabilizing agent for heavy metal-contaminated soil | Mixed with contaminated soil to immobilize heavy metal ions |
| Metallurgical Industry | Slag conditioner in steelmaking | Added to basic oxygen furnace or electric arc furnace slag to adjust basicity and fluidity |
Manufacturing Quality Control of Calcium metasilicate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Major Component Content (CaO, SiO₂) | Acid-Base Titration / X-ray Fluorescence Spectroscopy (XRF) | Acid-base titration: The sample is dissolved in acid, and CaO content is determined by EDTA titration; SiO₂ is measured by gravimetric or spectrophotometric methods. XRF enables rapid, non-destructive determination of various oxide contents, suitable for batch sample analysis. |
| Purity | X-ray Diffraction Analysis (XRD) | Comparison of the XRD pattern with standard PDF cards to identify the presence of CaSiO₃ crystalline phase and impurity phases (e.g., CaCO₃, SiO₂, etc.), assessing phase purity. |
| Moisutre Content | Loss on Ignition (LOI) by Drying | The sample is dried at 105–110°C until constant weight; the weight loss percentage reflects the content of free water and some bound water. |
| Loss on Ignition (LOI) | High-Temperature Calcination | The sample is calcined in a furnace at 950–1000°C for a specified time; the mass loss is measured to evaluate volatile components and carbonate decomposition. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Utilizes laser scattering principles to measure particle size distribution in suspension or gas, assessing fineness and uniformity of the product. |
| Specific Surface Area | BET Nitrogen Adsorption Method | Determines the specific surface area of the material via physical adsorption of nitrogen, reflecting powder activity and dispersibility. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, AAS or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is used to determine concentrations of hazardous elements such as lead, cadmium, mercury, and arsenic, ensuring compliance with safety standards. |
| pH Value (Aqueous Suspension) | pH Meter Measurement | The calcium silicate is dispersed in deionized water at a specified ratio, stirred, allowed to settle, and the pH of the suspension is measured using a pH meter. |
| Whiteness | Whiteness Meter Measurement | Integral sphere whiteness meter measures the reflectance of the sample in the visible light range to evaluate appearance quality, commonly used for filler-grade products. |
| Impurity Elements | Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS) | Combines morphological observation with elemental analysis to qualitatively or semi-quantitatively detect the distribution of impurity elements in localized regions. |
