Ultrafine Silica Powder for Precision Ceramics & Technical Glass
Fine silica powder for precision ceramic bodies, technical glass batches and other silica-rich formulations. Controlled grinding, particle-size options and low-iron chemistry support clean mineral addition where batch consistency and appearance matter. Final grade should be matched to the customer’s firing or melting process.
ULTRAFINE SILICA FOR PRECISION MATERIALS
Ultrafine Silica Powder for Precision Ceramics & Technical Glass
A fine crystalline silica powder for precision ceramic bodies, technical glass batches and silica-rich formulations. Controlled grinding, selectable fine grades and low-iron chemistry support clean mineral addition where particle distribution, batch consistency and appearance are important.
Product Overview
This ultrafine silica powder is produced from selected quartz raw material through fine grinding and controlled classification. It is supplied as a dry mineral raw material for precision ceramic formulations, technical glass batches, ceramic glazes and selected refractory systems.
Fine mineral addition can influence packing, slurry preparation and the balance of silica in a batch. The right grade depends on the customer’s binder, other raw materials, forming method, firing or melting schedule and required final properties. The product is not a finished glass powder, molten-glass product or ceramic component.
Technical Properties
| Property | Typical Specification | Order Note |
|---|---|---|
| Material | Micronized crystalline silica | Specify phase requirements separately if needed |
| Mesh options | 1000–3000 mesh | Select according to batch and forming process |
| Particle size (μm) | Nominal sieve range approximately 13–5 μm | Final PSD and test method to be agreed |
| SiO₂ content | 99.3–99.7% | Approved crystalline silica range |
| Fe₂O₃ | <0.015% | Low-iron specification; confirm method |
| Moisture | <0.1% | Keep sealed and dry after delivery |
| Whiteness | 92–95 | Confirm method for appearance-critical batches |
| Specific gravity | 2.65 g/cm³ | Use for batch and solids-loading calculations |
Particle-size note: Mesh is a commercial screening reference, not a complete particle-size distribution. If slurry rheology, packing density or melting behavior is critical, specify D10, D50, D90, top-cut or residue limits together with the test method.
Ultrafine Grinding and Classification
Fine grinding reduces the selected quartz feed, while classification separates the requested commercial grade. Clean handling and controlled collection help maintain the agreed mineral chemistry and support repeatable particle-size supply. The release plan can include particle-size, moisture, whiteness and chemistry checks.
Properties and Application Value
| Powder Attribute | Formulation Role | Typical Use |
|---|---|---|
| Fine particle-size options | Support controlled powder packing and batch preparation | Precision ceramic bodies and technical ceramics |
| Low-iron chemistry | Helps limit iron introduced with the silica raw material | Light-colored ceramics and selected glass batches |
| High SiO₂ content | Provides a defined silica-bearing mineral input | Silica-rich technical glass and ceramic formulations |
| Controlled dry supply | Supports repeatable weighing, dispersion and storage | Glaze, refractory and specialty mineral mixes |
Particle-Size, Chemistry and Packing Control
Representative samples can be evaluated against the agreed particle-size, chemistry and moisture methods before release. Moisture-barrier liners and sealed paper drums help preserve the powder during storage and shipment. Packing configuration is selected according to handling equipment, order quantity and export conditions.
- Batch identification and retained samples support shipment traceability.
- Particle-size testing can follow an agreed sieve, laser-diffraction or residue method.
- Low-iron and moisture requirements can be confirmed against the approved specification.
- Store sealed in a dry area and follow the SDS and local dust-control requirements during transfer.
Information Needed for Grade Selection
- Precision ceramic, technical-glass, glaze or refractory application.
- Required mesh grade, PSD or screen-residue test method.
- Target SiO₂, Fe₂O₃, whiteness and moisture limits.
- Binder, forming, firing or melting process and expected batch volume.
- Trial quantity, regular demand and packing requirements.
