| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Loss on Ignition (LOI) | Thermogravimetric Analysis (TGA) | Measures mass loss upon heating to remove adsorbed water and structural hydroxyl groups. |
| SiO2 Content | Acid Decomposition followed by Gravimetric Analysis | Silica is precipitated as hydrated SiO2 after HF-H2SO4 digestion and weighed. |
| MgO Content | EDTA Complexometric Titration | Magnesium ions are chelated with EDTA at pH 10 using Eriochrome Black T indicator. |
| Li2O Content | Flame Photometry | Lithium emission intensity at 670.8 nm is measured in a flame and quantified against standards. |
| Fe2O3 Content | UV-Vis Spectrophotometry (o-Phenanthroline method) | Ferrous complex formed after reduction absorbs at 510 nm; proportional to total iron. |
| Al2O3 Content | ICP-OES | Aluminum concentration determined by atomic emission intensity at characteristic wavelength (e.g., 396.15 nm). |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Multi-element detection based on mass-to-charge ratio after acid digestion and plasma ionization. |
| Particle Size Distribution | Laser Diffraction | Measures angular scattering pattern of dispersed particles to calculate size distribution. |
| Specific Surface Area (BET) | Gas Adsorption (N2 BET Method) | Determines surface area from nitrogen adsorption isotherm using Brunauer-Emmett-Teller theory. |
| pH of 1% Aqueous Suspension | Potentiometric Measurement | Electrode-based measurement of hydrogen ion activity in standardized suspension. |
| Viscosity (1% Dispersion) | Rotational Viscometry | Shear stress response measured under controlled shear rate using spindle-type viscometer. |
| Whiteness Index | Reflectance Spectrophotometry | Calculated from tristimulus reflectance values (CIE L, a, b*) at 45/0 geometry. |

1. How do you ensure product quality consistency?
We rely on a mature China-based manufacturing system and implement strict batch control and quality inspection for every shipment. Our production process complies with ISO 9001 standards, and a COA is provided for each batch to ensure consistent and reliable quality.
2. Do you offer competitive pricing for bulk orders?
Yes, as a China-based manufacturer and bulk supplier, we provide tiered pricing based on order volume. We support FOB and CIF quotations, as well as L/C payment terms for large transactions to meet international trade requirements.
3. Can you support large-volume or long-term supply?
We have stable production capacity and a well-established supply chain, enabling continuous bulk supply. We support ton-level and container-level orders, as well as long-term cooperation projects.
4. What is your typical lead time?
For in-stock products, shipment can be arranged within 1–3 days. For bulk packaging or customized orders, lead time depends on the specific quantity and production schedule.
5. What documents do you provide?
We can provide complete documentation upon request, including COA, SDS, TDS, and other compliance certificates, meeting industrial procurement and export requirements.
6. Can you customize product specifications or packaging?
Yes, we support customization of parameters such as purity, impurities, residual solvents, and heavy metals. We also offer various bulk packaging options, including 25kg bags, drums, and IBC tanks, suitable for industrial applications and transportation.
7. What shipping options do you support?
We support both FCL (Full Container Load) and LCL (Less than Container Load) shipments, and can flexibly arrange logistics solutions based on order size to meet bulk chemical export needs.
8. Do you provide technical or application support?
Yes, we provide basic application guidance and technical support based on industry experience to help customers optimize product usage.
9. How do you handle compliance and export regulations?
