Industrial Applications of Silica glass
| Industry | Application | Process |
|---|---|---|
| Rubber Industry | Reinforcing filler | Mixed with rubber to enhance abrasion resistance, tear strength, and reinforcement properties |
| Toothpaste Manufacturing | Abrasive | Removes surface stains and dental plaque through mechanical abrasion |
| Cosmetics | Adsorbent/Filler | Used in products such as foundations to absorb excess sebum and impart a smooth texture |
| Food Processing | Anti-caking agent | Added to powdered food products (e.g., sugar, milk powder) to prevent caking |
| Pharmaceuticals | Drug carrier | Employed as a pharmaceutical excipient to facilitate drug release and absorption |
| Paints & Coatings | Thickener/Anti-settling agent | Improves paint rheology and prevents pigment settling |
| Electronic Materials | Insulating layer | Applied in the fabrication of insulating coatings for semiconductor devices |
| Paper Production | Filling agent | Enhances paper whiteness and smoothness, improving print quality |
| Agriculture | Soil conditioner | Improves soil structure and enhances water and nutrient retention capacity |
Manufacturing Quality Control of Silica glass
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and condition of the sample under natural light or standard light sources to determine if it is a white powder, free from clumping and foreign matter. |
| Particle Size Distribution | Laser Particle Size Analysis | Determine the particle size distribution using the principle of laser scattering in liquid or gas, assessing the product's uniformity and fineness. |
| Specific Surface Area | BET Nitrogen Adsorption Method | Determine the specific surface area by measuring the physical adsorption of nitrogen at low temperatures and calculating using the BET equation, reflecting the material's porosity and activity. |
| pH Value | pH Meter Measurement | Disperse the sample in deionized water (usually 10% suspension) and measure its acidity or alkalinity using a pH meter to control product stability. |
| Moisture Content | Karl Fischer Titration | Determine the moisture content precisely by measuring the quantitative reaction between iodine, sulfur dioxide, pyridine, and methanol with water. |
| Loss on Ignition (LOI) | Weight Method (High-Temperature Combustion) | Heat the sample at high temperature (e.g., 800–1000°C) for a certain period, and calculate the volatile content based on the difference in mass before and after combustion. |
| Heavy Metal Content | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Dissolve the sample and determine the content of heavy metals such as lead, arsenic, mercury, and cadmium to ensure compliance with pharmacopoeia or food-grade standards. |
| Silicon Content (SiO₂) | Gravimetric Method or Fluorosilicic Acid Potassium Titration | After alkali fusion or acid dissolution, determine the actual content of silicon dioxide through precipitation, titration, or instrumental analysis. |
| Chloride | Argentometric Titration | Add silver nitrate to the sample solution to form silver chloride precipitate; quantitatively determine chloride residues using turbidimetry or titration. |
| Sulfate | Turbidimetric Method | In acidic conditions, add barium chloride to form barium sulfate precipitate, and determine sulfate content via turbidity measurement. |
| Microbial Limits | Microbial Cultivation Method | Perform tests for aerobic bacteria, mold, and Escherichia coli according to pharmacopoeia requirements to ensure product microbial safety. |
| Powder Density / Tap Density | Cylinder Method (Shaking Measurement) | Determine the mass per unit volume of the powder, recording the values before and after shaking (tap density). |
| Dispersibility | Ultrasonic Dispersion Combined with Particle Size or Viscosity Measurement | After ultrasonic treatment in a liquid, observe the dispersion stability or assess dispersibility through changes in viscosity. |
