High-purity · spherical · plasma-processed nano
High-purity raw materials, in-house milling and classification, and thermal or plasma processing support three silica powder families. Chemistry, particle size and morphology are matched to the application.
The capability combination
Many powder processors can reduce particle size. Jingui's differentiation is the combination of clean raw material, particle equipment, thermal or plasma engineering and in-house measurement—allowing three demanding families to be developed within one technical platform.
High-purity feedstock is processed through a contamination-controlled micronization and classification route. The product is qualified through the complete trace-element profile and particle distribution—not by whiteness or one nominal size alone.
Core controls · impurity profile · D10/D50/D90 · coarse-particle tail · lot consistency
The route combines morphology engineering with particle classification. Sphericity, multimodal distribution, flow and resin-system compatibility are evaluated together for high-filled electronic packaging and copper-clad laminate formulations.
Core controls · sphericity · packing density · flow · oversize control · surface compatibility
Plasma deflagration is followed by collection, deagglomeration, classification and final testing. Silica Bloom describes the intermediate morphology; the supplied product is the processed nano silica powder.

High-purity and spherical grades are supported by the silica-powder platform, while the plasma-processed nano route has its own dedicated production capacity.
High-purity and spherical grade development
Plasma-processed nano material route
Technology + equipment barrier
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.
Build the micron-scale particle distribution without relying only on external toll processing.
Control the coarse tail, fines and usable distribution after each material-forming step.
Create spherical morphology or nanoscale architecture through the route required by the product.
Use impurity and particle data to adjust the next production batch.
High-purity powder · representative data
The company-supplied C616 record covers a nominal 5 μm silica sample. The data is shown directly for technical screening, with its limits stated clearly instead of being converted into an unsupported purity claim.

Application-specific selection
The same SiO₂ chemistry can serve very different functions. Final selection follows the resin, loading level, dispersion method, reliability requirement and acceptance test used downstream.
Application fields describe development and qualification directions. Commercial use remains subject to grade-specific testing in the customer's actual system.
Intermediate—not final product
Plasma deflagration forms the flower-like intermediate known as Silica Bloom. The open, hollow morphology belongs to this process stage. The supplied product is nano silica powder after collection, deagglomeration, classification and inspection.
Final supplied gradeAfter the bloom
The visible intermediate is collected, deagglomerated and classified before the final material is released.
