01 / Laboratory capability

Measure trace impurities before they become a process problem.

The Agilent 5900 ICP-OES is used to measure elemental content in quartz materials. The current analytical workflow covers 13 trace elements—including Fe, Ti, Al and Li—and supports ppm-level impurity evaluation. Reporting limits are confirmed for each element, sample matrix and test method.

02 / Particle distribution

Particle control is a distribution—not one nominal size.

D10, D50 and D90 describe the fine end, median and coarse end of a particle population. This is more useful than a single mesh designation because distribution affects packing, dispersion, melting behaviour and the stability of a customer's process.

The complete curve is used to adjust milling and classification conditions and to verify that repeated batches remain within the agreed particle window.

03 / Performance verification

Verify what the material does after processing.

Chemical purity and particle data explain only part of performance. Optical-transmission comparison and controlled melting observations help show how a material responds after it enters a downstream process.

  • Optical responseCompare transmission behaviour across the measured wavelength range.
  • Melting observationObserve the condition and appearance of samples after controlled heating.
  • Material comparisonConnect changes in the material route with differences in downstream performance.

From breakthrough to volume production

Two production routes prove two different kinds of control.

High-purity quartz development focuses on impurity removal and contamination control. Nano silica development uses plasma deflagration, followed by collection, deagglomeration and classification to control particle characteristics.

Jingui produces 6N crystalline quartz sand and nano silica powder. Purity and particle specifications are evaluated separately for each product.
01 / Natural quartz purification6N

Ultra-pure quartz sand at production scale

The route begins with the mineral itself. Ore evaluation, targeted impurity removal, contamination isolation and batch testing are linked into one controlled process, connecting selected quartz feedstock with repeatable ultra-pure production.

Finished-sand test records are available on the high-purity quartz page.
02 / Plasma particle engineeringNANO

Nano silica powder for volume production

Plasma deflagration produces the silica intermediate. Subsequent collection, deagglomeration and classification prepare the powder for chemistry and particle-size verification before release.

Capability focus · nanoscale particle formation, agglomeration control and repeatable final distribution.
Milling, classification and contamination control

Batch or continuous ball milling is paired with air classification for the appropriate powder route. Coarse material returns for regrinding. Ceramic contact surfaces, magnetic separation and batch testing help control wear-related contamination; equipment and lining materials are selected for the target impurity specification.

Process intermediateSilica BloomSilica Bloom is the light, flower-like intermediate formed during plasma deflagration. Its open, hollow appearance describes this process stage, not the internal structure of the final powder particles.

Plasma deflagration

A visible intermediate in the nano-silica process.

Plasma deflagration produces a loose, flower-like silica intermediate. Collection, deagglomeration and classification follow, with chemistry and particle characteristics verified on the finished nano silica powder.
