Description

Cement, Alumina, Chemicals CAS NO 65997-16-2 refers to a specialized class of high-alumina cementitious materials, primarily composed of calcium aluminates. This product is engineered for superior performance in demanding environments where standard Portland cement is insufficient. It is a critical material for industries requiring rapid strength development, high-temperature resistance, and exceptional durability. Key sectors include advanced refractories, specialized construction, and high-performance ceramics manufacturing.

Application

• Refractory Castables and Monolithics: As a key hydraulic binder in formulations for furnace linings, kiln furniture, and other high-temperature industrial applications.
• Rapid Repair and Construction: For emergency repairs, marine construction, and cold-weather concreting where fast setting and early high strength are paramount.
• Chemical-Resistant Structures: In the construction of floors, containment vessels, and pipes in chemical plants due to its resistance to sulfate and mild acid attack.
• Advanced Ceramics and Composites: As a precursor or bonding phase in the production of technical ceramics and ceramic-matrix composites.
• Waste Immobilization: Used in solidification/stabilization processes for hazardous and radioactive wastes.
• Oil Well Cementing: For specialized downhole applications requiring specific setting profiles and durability under high pressure and temperature (HPHT) conditions.

Quality Control

Our Calcium Aluminate Cement is manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified against key parameters including chemical composition (Al2O3, CaO, SiO2 content), setting time, and compressive strength development. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment. Our production adheres to relevant industry standards such as EN 14647.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area. Keep containers tightly sealed when not in use to prevent moisture absorption and premature setting. Store away from incompatible materials. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F).
