Product Description
Alumina Seal Ceramic Rings / Industry Insulation Rings
1. Description:
Applications of Ceramic Seal Rings:
1) Electrical seal systems: The highest performance electrical seal systems employ Ceramic Seal Ring for its exceptional resistance to thermal and mechanical shock, as well as corrosion.
2) Medical implant devices: exceptional corrosion resistance and biocompatibility are required by medical implant devices. Ceramic Seal Ring plays a critical role in implantable electronic devices. Researchers and doctors have created a wide array of implantable electronic devices including defibrillators, cochlear implants, and neurostimulators. Feedthroughs for implanted devices must be hermetic, with a leak-tight ceramic seal ring around each pin.
2. Feature Advantages:
1) Refractory, High Temperature Resistance, Maximum Used Temperature: 1800 ºC (3272ºF)
2) Hardness Strength, Wear Resistance Up To Mohz 9.0 ; HRA 80-90
3) High Voltage, Good Insulation Performance ,Electrical Resistivity Up To 10∧14 Ohm.Cm
4) High Polished Surface Up To Rz0.8(Ra0.1)
5) Superior Mechanical Strength, MAX 10 MPa.m1/2 Fracture toughness
6) Pressure Resistance, Max 2300MPa compressive strength
7) Anti-High Corrosion Resistance, Such As Acid Alkali Resistance
8) Long Service Life
9) Other excellent property
