| Industry | Application | Process |
|---|---|---|
| Chemical Raw Materials | Dimethylchlorosilane reagent | Flux calcination |
| Catalyst Supports | Enhancing catalytic reaction efficiency | Flux calcination |
| Functional Fillers | Improving performance of polymer composites | Flux calcination |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Loss on Ignition (LOI) | Thermogravimetric Analysis (TGA) | Measures mass loss upon heating to decompose volatile components and drive off moisture and carbonates. |
| Silicon Dioxide (SiO2) Content | Acid-Base Titration after Fusion | Fuses sample with sodium carbonate, dissolves in acid, precipitates silica as SiO2.xH2O, then dehydrates and weighs. |
| Iron Oxide (Fe2O3) Content | ICP-OES | Digests sample in HF-HNO3 mixture, measures Fe emission intensity at characteristic wavelength. |
| Aluminum Oxide (Al2O3) Content | ICP-OES | Same digestion as Fe2O3; quantifies Al via atomic emission at specific wavelength. |
| Calcium Oxide (CaO) Content | Flame Atomic Absorption Spectroscopy (FAAS) | After acid digestion, measures Ca absorption at 422.7 nm using air-acetylene flame. |
| Magnesium Oxide (MgO) Content | FAAS | Measures Mg absorption at 285.2 nm following acid digestion and dilution. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential jump. |
| Surface Area (BET) | Gas Adsorption (N2 BET) | Measures N2 adsorption isotherm at 77 K to calculate specific surface area using Brunauer-Emmett-Teller theory. |
| Particle Size Distribution | Laser Diffraction | Analyzes angular scattering pattern of laser beam passed through dispersed sample to compute size distribution. |
| pH of Aqueous Slurry | pH Meter Measurement | Measures hydrogen ion activity in 10% w/w aqueous suspension after equilibration. |
| Residual Chlorosilanes | Gas Chromatography (GC-FID) | Quantifies volatile chlorosilane impurities (e.g., Me2SiCl2) using flame ionization detection. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemically generates iodine to react stoichiometrically with water; quantifies water via charge consumed. |

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?
