High-purity · spherical · plasma-processed nano
We develop three silica powder families using high-purity raw materials, in-house milling and classification, and thermal or plasma processing. Composition, particle size and shape are selected for the application.
Integrated processing capabilities
Jingui combines high-purity feedstock, milling and classification equipment, thermal and plasma processing, and in-house analysis to develop three silica powder families.
High-purity feedstock is micronised and classified with contamination control. We evaluate the full trace-element profile and particle-size distribution, as well as whiteness and nominal size.

Particle-shape engineering and classification are combined to meet formulation requirements. We assess sphericity, multimodal size distribution, flow and resin compatibility for highly filled electronic packaging and copper-clad laminates.

High-temperature plasma deflagration converts high-purity sand from our own quartz resources into 20 nm spherical silica at 99.9997% purity.
20 nm spherical silica · 99.9997% purity · Physical production processSpherical powder · High-temperature plasma deflagration
We use high-purity sand from our own quartz resources to produce 20 nm spherical silica at 99.9997% purity through a physical process. Managing the raw material and powder production supports cost advantages at scale.
From quartz resource to nano powder
High-temperature plasma deflagration differs from conventional fumed-silica production by flame hydrolysis of silicon tetrachloride. The powder is loosely agglomerated, with a reported particle size range of 15.9–41.97 nm.

Process and equipment expertise
Jet milling and classification control micron-scale size distribution. Spherical and nano silica use the forming process suited to each material, followed by classification, impurity testing and particle verification.
Our own milling equipment gives us direct control over micron-scale particle distributions.
Manage coarse particles, fines and the usable size range after particle formation.
Use product-specific processes to produce spherical particles or nanoscale structures.
Impurity and particle measurements guide adjustments to the next production batch.
Application-specific selection
The same SiO₂ composition can perform different functions. Select the grade for the resin, filler loading, dispersion method, reliability criteria and acceptance tests in your process.
These are areas for development and qualification. Commercial use requires grade-specific testing in the customer's actual system.
High-temperature plasma deflagration
We use high-purity sand from our own quartz resources to produce 20 nm spherical silica at commercial scale through a physical process. Silica Bloom shows the material during processing; the supplied powder is loosely agglomerated.
