Specification of High Purity 99.99% Aluminum Nitride Ceramics by Gravel, Moulding Plus Machining

High purity aluminum nitride ceramic offers exceptional performance. This material reaches 99.99% purity. Such high purity is critical. It directly impacts the material’s thermal and electrical properties. We produce it using gravel processing, moulding, and precision machining. Each step is vital.

Gravel processing starts with raw materials. We carefully crush and refine aluminum nitride powder. This step removes impurities effectively. High purity demands this rigorous initial processing. Clean powder is the foundation. Moulding comes next. We shape the purified powder into the desired forms. Different moulding techniques are available. We select the best method for the part geometry. This forms a “green” body. Then we sinter it. Sintering heats the part to very high temperatures. This makes the ceramic dense and strong.

Machining is the final step. We machine the sintered ceramic parts precisely. This achieves the exact dimensions needed. Tight tolerances are possible. Surface finishes are excellent. Machining ensures the parts fit perfectly in demanding applications.
