High-Performance Refractories: Serves as a key binder phase or aggregate in castables and refractory bricks, significantly enhancing high-temperature strength and erosion resistance.
Specialty Ceramics & Coatings: An excellent raw material for structural ceramics, electronic ceramics, and thermal barrier coatings, improving sintering performance and final mechanical properties.
Cement and Building Material Additives:Serves as a mineral admixture or early-strength component in specialty cement systems, regulating hydration processes to optimize long-term durability.
Fluorescent Material Matrix:Acts as an efficient luminescent matrix material, widely used in preparing long-afterglow phosphors for safety signage and low-light illumination applications.
Q1: What is the chemical stability of calcium aluminate powder, particularly its behavior in water?
A1: It exhibits good chemical inertness but undergoes slow hydration in water. Therefore, storage in a dry environment is recommended to prevent reactivity changes.
Q2: Does particle size distribution affect its performance in refractory materials?
A2: Yes. Particle size distribution directly influences bulk density, sintering activity, and final mechanical properties. We can recommend optimal particle size combinations tailored to your forming and sintering processes.
Q3: Can calcium aluminate with specific crystal structures be provided?
A3: Yes. By controlling raw materials and calcination processes, we can synthesize products with different crystal forms, tailored to your requirements for thermal properties or reactivity.
Q4: Are there special requirements for transporting and storing this product?
A4: This product requires moisture-proof sealed packaging. Store in a cool, dry warehouse and avoid mixing with acidic substances. Prevent packaging damage and moisture exposure during transportation.
