Additive Manufacturing: Light cured 3D printing technology enables direct molding of complex structural components with porosity<1%.

Intelligent sintering: AI dynamically regulates the sintering curve, reducing grain size deviation from ± 2 μ m to ± 0.5 μ m.

Engineering technology ceramics are shifting from "functional substitution" to "performance leadership", driving revolutionary upgrades in ultra high speed aircraft, nuclear 

energy systems, and implantable medical 

devices. With the development of nano modification, intelligent preparation and other technologies, this material family is expected to open up a billion dollar emerging market before 

2030.
