Industrial Applications of TSP
| Industry | Application | Process |
|---|---|---|
| Agriculture | Used as a high-concentration phosphorus fertilizer, supplying water-soluble phosphate readily available to plants | Produced by reacting phosphoric acid with phosphate rock powder; primary component is monocalcium phosphate (Ca(H₂PO₄)₂·H₂O), with minor free phosphoric acid; granulated and dried to yield granular fertilizer |
| Animal Feed Additives | Supplies phosphorus in compound animal feeds to support bone development and metabolic functions | Purified and blended into compound feeds at controlled ratios to meet animal nutritional phosphorus requirements |
| Food Industry (Indirect) | Intermediate for producing food-grade phosphate salts (requires further purification) | Chemically purified and recrystallized to remove heavy metals and impurities, then converted into food additives such as calcium phosphate compounds |
Manufacturing Quality Control of TSP
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Total P2O5 content | Acid-base titration after ammonium molybdate precipitation | Phosphate is precipitated as ammonium phosphomolybdate, dissolved in alkali, and titrated with standard acid. |
| Water-soluble P2O5 | Gravimetric analysis after extraction and precipitation | Water-soluble phosphate is extracted, precipitated as magnesium ammonium phosphate, and ignited to Mg2P2O7 for calculation. |
| Citric acid-soluble P2O5 | Spectrophotometry (UV-Vis) after ammonium molybdate reduction | Citric-soluble phosphate reacts with ammonium molybdate and ascorbic acid to form phosphomolybdenum blue complex measured at 880 nm. |
| Free acidity (as H3PO4) | Acid-base titration with phenolphthalein indicator | Free phosphoric acid is titrated directly with standardized NaOH solution to phenolphthalein endpoint. |
| Fluoride content | Ion-selective electrode (ISE) potentiometry | Fluoride ion activity is measured using a fluoride-specific electrode calibrated against standard solutions. |
| Heavy metals (Pb, Cd, As, Hg) | ICP-OES | Sample is acid-digested and elemental concentrations are determined by plasma emission intensity at characteristic wavelengths. |
| Moisture content | Thermogravimetric analysis (TGA) or oven drying at 105 C | Mass loss upon heating to constant weight at 105 C is used to calculate moisture content. |
| Particle size distribution | Dry sieving (standard test sieves) | Material is separated through a series of standardized mesh sieves and mass retained on each sieve is recorded. |
| Bulk density | Cylindrical cup method (ASTM D1895) | Mass of material freely poured into a calibrated cylinder is divided by the cylinder volume. |
| pH of 10% aqueous suspension | Potentiometric measurement with pH meter | pH is measured electrometrically in a well-mixed suspension of sample in distilled water. |
| Iron content | AAS (flame atomic absorption spectroscopy) | After acid digestion, iron concentration is quantified by absorption of light at 248.3 nm in an air-acetylene flame. |
| Sulfate content | Gravimetric analysis with barium chloride | Sulfate is precipitated as BaSO4, filtered, dried, and weighed to determine sulfate content. |

Industrial TSP Procurement FAQ
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?
We are familiar with international trade and export regulations, ensuring all products comply with relevant requirements. We also provide complete documentation to support smooth customs clearance and global delivery.
