Core Industrial Applications
1. Petrochemical & Molecular Sieve Synthesis
As a high-purity aluminum source, the 50# grade is ideal for the production of zeolites and molecular sieves. Its high reactive alumina content ensures efficient crystallization and structural integrity for petroleum hydrocarbon transformation catalysts and carriers.
2. High-Performance Construction Chemicals
Used as a premium concrete accelerator, especially in shotcrete and rapid-repair mortars. The high concentration allows for lower addition rates while achieving faster setting times in challenging underground or low-temperature environments.
3. Advanced Water Treatment
Effectively used for silica removal and as a secondary coagulant to enhance the removal of heavy metals and suspended solids. It adds necessary alkalinity to the system, optimizing the coagulation-flocculation process.
4. Specialty Chemical Manufacturing
- Titanium Dioxide: Provides a high-density alumina coating to improve pigment durability.
- Refractory Materials: Acts as a high-strength bonding agent in refractory cement and castables.
- Paper & Textile: Functions as a high-efficiency filler and antistatic agent in synthetic fiber production.
Quality Control & Packaging
- Consistency: Our 50# grade undergoes 18-mesh sieving to ensure a 90% pass rate, guaranteeing uniform particles and rapid, clump-free dissolution.
- Standard Packaging: 25KG inner plastic and outer woven bags.
- Bulk Options: 1000KG Jumbo bags or custom palletized packaging available for international shipping.
- Customization: We offer tailored molar ratios and packaging designs to meet specific industrial formulations.

Frequently Asked Questions (Technical Support)
Q: What makes the 50# model different from the 48# or 35#?
A: The 50# model contains the highest concentration of active Aluminum Oxide (≥50.0%) and Sodium Aluminate (≥80.0%). This means you get more reactive power per kilogram, making it more cost-effective for high-volume chemical synthesis and heavy-duty construction projects.
Q: How does the molar ratio (1.30±0.05) affect performance?
A: This precise caustic ratio ensures that the product remains highly stable during storage and provides a predictable, high-pH reaction environment when dissolved, preventing premature precipitation in sensitive catalyst formulations.
Q: What is the shelf life of the 50# solid product?
A: When stored in a cool, dry place in its original sealed packaging, the product typically has a shelf life of 12 months. Due to its hygroscopic nature, it is vital to keep the bags tightly closed.
