Description

Potassium Aluminate Trihydrate is a versatile inorganic salt widely used as a precursor and catalyst in advanced material synthesis. Its primary value lies in providing a soluble source of aluminate ions, which is critical for processes requiring controlled alumina deposition or alkaline reactivity. This compound is essential for manufacturers and R&D facilities in the ceramics, catalyst, and water treatment industries seeking consistent, high-purity intermediates.

Application

• Ceramics and Refractories: Acts as a key binder and fluxing agent in the production of advanced ceramics, refractory cements, and high-temperature materials.
• Catalyst Synthesis: Serves as a precursor for the preparation of alumina-based catalysts and catalyst supports used in petrochemical and fine chemical processes.
• Water Treatment: Utilized as a coagulant aid and for phosphate removal in industrial and municipal water purification systems.
• Molecular Sieves and Zeolites: Provides an aluminum source in the hydrothermal synthesis of zeolites and other aluminosilicate molecular sieves.
• Paper Manufacturing: Functions as a sizing agent to improve the water resistance and printability of paper products.
• Textile Processing: Used in mordanting and fireproofing treatments for fabrics.
• Construction Chemicals: Incorporated into specialty cements and concrete accelerators to modify setting times and properties.

Quality Control

Our Potassium Aluminate Trihydrate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and decomposition. Keep away from incompatible materials such as strong acids.
