Long Life Silicon Nitride Bonded Silicon Carbide Protection Sheath for Liquire Alumina

Long Life  silicon nitride bonded silicon carbide protection sheath for liquire alumina  

Silicon carbide products lines:

1. Reaction Sintered Silicon carbide (RBSIC)

2. Recrystallized Silicon Carbide ceramic (RSIC)

3. Nitride Bonded Silicon Carbide ceramic (NBSIC)

4. Sintered Silicon Carbide (SSiC)

1.  RBSIC thermocouple protection sheath 

RBSiC (SiSiC) rollers are used for the high temperature sintering zone of roller hearth kilns. The application includes kiln furniture for table wear porcelain, sanitary wear, construction ceramics, glasses and magnetic materials productions, etc. 

They have higher bearing strength, high temperature tolerance, corrosion resistance, wear resistance, and there are no deformation even under very high temperature. The tubes display more than 10 times operational life compared to Alumina tubes .

  the technical data

 2.NBSIC thermocouple protection sheath 

Si3N4 bonded SiC ceramic refractory material, is mixed with high pure SIC fine powder and Silicon powder, after slip casting course, reaction sintered under 1400~1500° C. During the sintering course, filling the high pure Nitrogen into the furnace, then the silicon will react with Nitrogen and generate Si3N4, So Si3N4 bonded SiC material is composed of silicon nitride (23%) and silicon carbide(75%) as main raw material, mixed with organic material, and shaped by mixture, extrusion or pouring, then made after drying and nitrogenization

Si3N4 bonded SiC as a new type refractory material, is used widely. The applying temperature is 1400 C. It has better thermal stability, thermal shock, which is better than plain refractory material and recrystallized SiC. It also has antioxidation, high corrosion resistant, wear-resistantance, high bending strength. It can resist corrosion and scouring, be no polluted and fast heat conduction in molten metal such as AL, Pb, Zn, Cu ect.
