5G Compatibility: Does not affect signal transmission at all, and performs excellently in weak signal areas such as elevators and basements.
Durability: Passes 1.2m drop tests with a 40% higher success rate than glass back panels, and exhibits outstanding scratch and wear resistance.
Heat Dissipation Performance: Effectively dissipates heat generated during phone operation, preventing performance degradation.
Aesthetic Value: Can be produced in various colors such as black, white, blue, and pink through doping processes, meeting personalized needs.
Zirconia Ceramic Mobile Phone Back Panel Product Introduction
Zirconia ceramic mobile phone back panels are rear cover components made from zirconia (ZrO₂) ceramic material, possessing the following significant characteristics:
1. Excellent Mechanical Properties: Flexural strength exceeding 1200 MPa (more than twice that of tempered glass), fracture toughness of 8±2 MPa*m¹/² (10 times that of glass), and elastic modulus of 200 GPa.
2. High Wear Resistance: Mohs hardness of 8-8.5, close to sapphire, far exceeding the 5-6 of tempered glass.
3. Excellent Signal Performance: No shielding of 5G/4G signals, low dielectric loss, particularly suitable for the needs of the 5G era.
4. Unique Texture: A warm, jade-like touch, with a thermal conductivity of 2-3 W/m·K, close to the comfortable range for the human body.
