Industrial Applications of Magnesium silicate
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antacid (to neutralize gastric acid); lubricant and filler in tablet formulations | Direct compression or compression after wet granulation |
| Food | Anti-caking agent (to prevent caking of powdered food products); clarifying agent (to adsorb impurities) | Direct addition to food or mixing with liquid followed by filtration |
| Cosmetics | Absorbent (for oil control); thickener (to enhance product stability) | Mixing with other ingredients followed by emulsification |
| Coatings & Paints | Suspension agent (to prevent pigment settling); rheology modifier | Incorporation into the system after high-speed dispersion or grinding |
| Plastics & Rubber | Filler (to improve mechanical properties); flame retardant (to reduce flammability) | Blending with other raw materials during internal or open mixing |
| Environmental Protection | Absorbent (for removal of heavy metals or organic pollutants from wastewater) | Direct dosing or packing into filtration columns |
| Ceramics | Flux (to lower firing temperature); strength enhancer (to improve green body strength) | Ball-milling, followed by shaping and sintering |
| Papermaking | Filler (to improve paper brightness and opacity); resin control agent | Mixing with pulp prior to sheet formation |
| Agriculture | Pesticide carrier (to improve dispersion); soil conditioner (to adjust pH) | Dry blending or spray granulation |
Manufacturing Quality Control of Magnesium silicate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Main Component Content (MgO, SiO₂) | Chemical Titration (e.g., EDTA titration, gravimetric method) | MgO is determined by EDTA complexometric titration; SiO₂ is measured by gravimetric method after acid dissolution or potassium fluorosilicate volumetric method. Used to calculate the purity of magnesium silicate. |
| Moisture Content | Loss on Drying (LOD) | Sample is dried at 105–110°C until constant weight; weight loss is measured to evaluate free water and crystalline water content. |
| Loss on Ignition (LOI) | High-Temperature Ignition Method | Sample is ignited in a furnace at 950–1000°C for a specified time; mass loss is measured to indicate structural water and volatile content. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measures particle size distribution based on laser scattering principles; evaluates fineness and uniformity, which affect application performance. |
| Specific Surface Area | BET Nitrogen Adsorption Method | Determines specific surface area through physical nitrogen adsorption; reflects powder activity and dispersibility. |
| Whiteness | Whiteness Meter Measurement | Uses an integrating sphere whiteness meter to measure sample reflectance of visible light; evaluates appearance quality. |
| Impurity Element Content (Fe, Al, Ca, etc.) | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | After dissolving the sample, trace metal impurities are measured using AAS or ICP-OES to control product purity. |
| pH Value | pH Measurement of Aqueous Suspension | Magnesium 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. |
| Oil Absorption Value | Dibutyl Phthalate (DBP) Absorption Method | Measures the amount of DBP absorbed per unit mass of magnesium silicate; reflects surface activity and filling performance. |
