In the vast field of materials science, ceramic materials have always held a significant position due to their unique properties, such as high hardness, excellent wear resistance, and good chemical stability. However, the brittleness of traditional ceramic materials limits their application in certain fields. To overcome this drawback, Pingxiang Chemshun Ceramics Co.,Ltd has continuously explored innovations. As a result, ZTA Zirconia-Alumina Composite Toughened Ceramic has emerged as a shining star in the field of advanced materials.

I. The Composition Secrets of ZTA Zirconia-Alumina Composite Toughened Ceramic

ZTA Zirconia-Alumina Composite Toughened Ceramic primarily consists of Al?O? and ZrO?, along with small amounts of Cr?O?, TiO?, and ZnO. These substances share similar crystal lattices and form solid solutions with Al?O? during sintering, playing critical roles. They refine grain structures, promote sintering, and enhance the fracture toughness of the ceramic.

II. Outstanding Performance Characteristics

High Hardness: The Rockwell hardness of ZTA ceramic is HRA ≥ 90, enabling it to maintain structural integrity when exposed to friction and impact from high-hardness substances, resisting scratches and wear.

Superior Wear Resistance: Thanks to its unique composition and toughening mechanisms, the wear volume of ZTA ceramic is ≤ 0.01. It delivers stable performance under prolonged, high-intensity wear conditions, significantly extending equipment service life and reducing maintenance costs.

Exceptional Impact Resistance: Through synergistic toughening mechanisms, ZTA ceramic effectively resists substantial impact forces, making it ideal for applications requiring impact load endurance.

Corrosion Resistance: ZTA ceramic maintains stable chemical properties in acidic and alkaline environments with a pH range of 3–12, making it suitable for industries like chemical processing, food, and pharmaceuticals.

Excellent Stability: With a smooth and regular shape, ZTA ceramic retains stable physical and chemical properties under varying temperatures and humidity levels, ensuring reliability in complex environments.

High Strength: Its flexural strength ranges from 300–800 MPa, and its compressive strength reaches 1,200–3,000 MPa, allowing it to withstand significant external forces and meet demanding engineering requirements.

III. Broad Application Fields

Industrial Wear Protection: ZTA composite ceramic wear-resistant liners are widely used in heavy-wear equipment handling large material volumes and impacts, such as mining machinery, metallurgical equipment, and coal transportation systems in the power industry. They serve as protective linings to reduce wear and improve operational efficiency.

Grinding Applications: ZTA composite ceramic balls act as high-performance grinding media in multiple industries.

Coatings and Inks: Used for grinding pigments and dyes, they enhance product dispersibility and stability, improving paint application performance and ink print quality.

Non-Ferrous Minerals and Non-Metallic Powders: Efficiently disperses and grinds materials in mineral processing and industrial ceramic powder production, boosting productivity and product quality.

Paper and Ink Industries: Improves paper uniformity and ink fineness for superior end products.

Chemical and Mining Sectors: Used in chemical reactors, catalyst carriers, and as grinding media in mining equipment, adapting to complex industrial environments.

Protection Applications: Alumina bulletproof ceramic plates, partially made of ZTA ceramic, can be customized into squares, hexagons, arcs, spheres, and irregular shapes. With high hardness, tight dimensional tolerances, moderate density, and strong ballistic resistance, they are applied in body armor, vehicle armor, building bunkers, and other safety-critical scenarios.
