A new production line for pressureless sintered silicon carbide ceramics, with an annual capacity of 600 metric tons, has started trial operation at Zhejiang Jingtao Technology, located in the Longquan Economic Development Zone in Lishui, Zhejiang province.

This production line not only improves the quality and yield of celadon products, but also marks a breakthrough in Longquan's production of specialized ceramics, which are suitable for applications in frontier fields, including aerospace.

The centuries-old Longquan celadon industry is quickly transitioning from traditional workshops to modern industrial production. Previously, the uneven quality of raw materials and non-standardized clay formulas hindered large-scale development.

In 2022, Longquan established the Longquan Celadon Resource Development Service, a company that acts as a centralized supplier and quality control hub, conducting precise material analysis, building a database, and developing standardized clay formulas to strengthen the industry's foundation.

Longquan is creating a collaborative and efficient modern industrial ecosystem. It is now home to over 4,600 celadon businesses, employing more than 20,000 people. In 2024, the industry's added value reached 822 million yuan ($114.9 million), a year-on-year increase of 10.6 percent.

Talent development is also a priority. Longquan has established a multi-level training system spanning vocational schools, higher education institutions, and master studios to ensure a sustainable talent pipeline.
