COMPONENT
PV silver-powder feedstock family
Ningbo Jingxin Electronic Materials ↗Jingxin's silver powders feed PV conductive-paste production. The catalogue covers several particle shapes, and the 516 micrograph gives a clear picture of the spherical type. Chemistry and size distribution for your lot come on the grade sheet and certificate.
A family of powder grades for paste makers. It is an ingredient: paste, printing and firing equipment come from other suppliers. Ask for the numeric data sheet of each grade you shortlist, and expect different grades to suit different cells.
General illustration of cell production equipment, not a photograph of this model. Ask the manufacturer for current photographs and layout drawings of the configuration offered.
START WITH YOUR PRODUCTION TASK
Name the electrode and paste formula, get a controlled grade sheet and a lot sample, then compare powder data and paste and cell results under agreed methods on your own line.
SOURCE-LINKED DATA
Published specifications
Values below are published by the manufacturer, each with the date its source was checked. Ask for the figures that apply to your configuration and material in the quotation.
The manufacturer has not published a complete specification table for this entry. Request the delivered material specification, drawing where applicable and lot acceptance requirements.
01 · Manufacturer information
What you are buying: the silver inside the paste
Jingxin and the Ningbo Fuda filing both describe front and rear PV silver powders made for conductive-paste production. That makes this an input to your formulation. Paste composition, rheology, firing profile and the finished cell result depend on the formula and process you build around it.
Jingxin also lists electronics uses outside solar. State your cell architecture and electrode position in the enquiry. TOPCon, HJT, PERC or back-contact suitability, and any efficiency gain, are decided by trials on your own cell process.

Four particle shapes in the current catalogue
| Particle shape | Grade names | Question to ask |
|---|---|---|
| Micron flakes | 8C | Which flake size range and paste role does 8C target? |
| Spherical | 16M, 9N, 516, 517, 16W | Where do these grades differ in chemistry, treatment and size? |
| Nano | JW-101 | What measured size and dispersion steps does JW-101 need? |
| Single crystal | SC5001 | Which structure data and applications come with SC5001? |

Reading the 516 micrograph
Particle shape
Jingxin labels the image as spherical silver powder 516. Magnification is 5000× with a 5 µm bar in the corner, a good guide to what the spherical grades look like.
Size distribution
A single microscope field gives no D10, D50 or D90. Ask for the distribution method, sample preparation and lot data instead.
Chemistry
Purity, impurities, surface treatment and moisture need an assay. Request the controlled specification and the certificate for each shipment.
Fit with your paste
The image carries no information about your formula, cell design or production lot. A traceable sample run through your own paste and process answers that.

Data to collect before you approve a sample
| Data group | Ask Jingxin for | Why it matters |
|---|---|---|
| Application | Recommended cell, electrode and paste route | Each grade suits particular pastes and cells. |
| Composition | Silver and impurity limits with test methods | Acceptance rests on measured results. |
| Particles | Distribution, shape, sampling plan and methods | Repeatable measurements let you compare lots. |
| Surface and handling | Treatment, moisture, volatiles and physical properties | These shape how the powder behaves in mixing. |
| Lot release | Certificate, traceability and reference sample plan | Repeat orders can be checked against the approved lot. |
| Packaging | Pack type, storage, expiry and opened-container rules | Handling advice should match the grade you buy. |

Trial plan from sample to production
Describe the job
Tell Jingxin your cell, electrode, paste formula, current process and target results, and ask for a grade recommendation with a data sheet.
Agree the sample paperwork
Settle chemistry, size distribution, treatment and test methods. Log lot, sampling and preparation so later lots are measured the same way.
Make trial paste
Record lots of every constituent, mixing and dispersion steps and formula settings. Set handling and printing targets; solids loading and mixing recipe are yours to develop.
Run it on your cells
Print and fire, or use your other qualified process, and log the stack and settings. Agree electrical and mechanical targets with engineering before judging the grade. Run the printed cells through the same testing and inspection set-up you use for your current paste, so each grade is judged on one yardstick.
Release repeat shipments
Keep the approved sample data, lot certificates, process records and pack instructions together. Ask Jingxin to notify you of particle, treatment, process or site changes.

Buyer questions on Jingxin silver powder
Can I order this as finished paste?
The listing is powder. Finished paste needs its own composition and process sheet from a paste maker.
Is 516 the only grade?
No. It is one of five spherical grades in a catalogue that also has flake, nano and single-crystal powders, and each grade has its own properties.
Can I work out particle size from the image?
Use Jingxin's measured distribution and sampling data for the lot you receive.
Does Jingxin offer an HJT low-temperature grade?
The low-temperature category has no working page and no HJT grade data is public. Ask Jingxin directly for any low-temperature grade and its results.
What lead time can I expect?
The 2023 output figure on the homepage describes past production. Ask for a quotation with a delivery date for your grade and volume.
