Engineering Structural Ceramic Parts Feature
Engineering structural ceramics were created to meet the material needs of rapidly developing technologies such as industrial automation, intelligent machinery, aerospace, aviation, and atomic energy, giving full play to the mechanical properties of ceramics that are different from those of metals and plastics.
Application of wear-resistant materials, abrasives, etc.
Gas turbine components, refractory and corrosion-resistant materials, cutting tools, etc.
Application of device ceramics, circuit substrates, mold materials, and cutting tools.
Refractory materials in metallurgical metals, high-temperature anion conductors, sensors, cutting tools and other application environments.
Mainly use three materials: alumina, zirconium oxide and aluminum nitride.
The product cannot be used directly after sintering and requires secondary machining, such as cutting, punching, grinding, lapping and polishing, to achieve the required shape and dimensional accuracy.
Quality and Reliability of Engineering Ceramic Parts
The manufacturing of engineering ceramic products differs somewhat from that of other ceramic parts. Due to their complex structures, injection molding is typically used, but tape casting and dry pressing can also be used to create simple structures, followed by secondary machining to create more complex structures. Due to the inherent rigidity and brittleness of ceramics, high-temperature sintered ceramic products are often processed using surface grinding, cylindrical grinding, centerless grinding, CNC precision machining, and laser machining to improve product precision and facilitate the manufacture of complex shapes and tight tolerances.

Ceramic parts generally outperform metals and engineering plastics in terms of wear resistance, corrosion resistance, rigidity, and high-temperature stability. In high-speed, high-load environments or those containing corrosive media, ceramic parts can significantly reduce wear rates, extend equipment maintenance cycles, and minimize downtime due to parts replacement, thereby improving overall equipment efficiency and long-term operational economy.
Alumina ceramics offer excellent overall performance and cost-effectiveness, making them suitable for most wear-resistant, insulating, and general corrosive environments. Zirconia ceramics, on the other hand, are renowned for their high fracture toughness and superior wear resistance, with a mechanical strength approximately twice that of alumina. They are better suited for critical components subjected to impact loads, stress concentrations, or where extremely high reliability is required. The choice between these ceramics and alumina ceramics requires comprehensive consideration of specific operating conditions, performance requirements, and budget.
While engineering structural ceramics emphasize their physical and mechanical properties, functional ceramics prioritize non-mechanical properties. These materials typically possess one or more functions, such as electrical, magnetic, optical, thermal, chemical, and biological. Some ceramic materials, such as zirconium oxide, aluminum oxide, and silicon nitride, are both structural and functional.
