Product Description

Alumina Seal Ceramic Rings / Industry Insulation Rings

 

1. Description:

Processing of ceramic seal rings:

Sintering --- To complete the forming process, manufacturers put the ceramic piece, known as a greenware, in an extremely oven or chimney. Sintering strengthens a ceramic part by causing its oxides to bond and desificate. During this chemical change, both ionic and covalent bonds are formed and create the ceramic’s crystal structure. This process involves cations; the ionic structure is determined when you calculate the difference of electronegativity between cations and anions.
 

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
