High-quality silicon carbide powder is pressed into green bodies of precise dimensions using isostatic or dry pressing technology, guaranteeing uniformity in density and shape.

Moisture is gradually removed from the green bodies in a controlled environment to prevent cracking and prepare them for high-temperature sintering.

Silicification and recrystallization sintering are carried out in ultra-high temperature induction furnaces. This efficient and uniform process is key to endowing the elements with high strength, purity, and stable thermoelectric properties.

The sintered hot zone is precisely joined with specially manufactured cold ends. This step ensures robust mechanical structure and reliable electrical current transfer.

The joints are welded under vacuum or protective atmosphere to form a dense, oxidation-resistant, low-resistance permanent bond.

Each element is individually packed using moisture-proof and shock-absorbent materials to ensure safety and integrity during transportation and storage.
