“CERAMIC FIBERS” : 

“CERAMIC FIBERS”

WHAT IS CERAMIC FIBER ? : 

WHAT IS CERAMIC FIBER ? Metal oxide fibers Si-C-O or Si-C-N-O AND Al2O3 and SiO2 >97% (Al2O3: 47%), Fe2O3: < 1.1% light weight refractory material , INSULATION …..

SPUN BOND SYNTHESIS : 

SPUN BOND SYNTHESIS

SYNTHESIS : 

SYNTHESIS

Different grades and varieties of ceramic fibers:- : 

Different grades and varieties of ceramic fibers:- Standard (NORMAL) Zirconia Fiber Glass Reinforced S.S wire Reinforced Cerafiber, Standard Cerachemfiber, Zirconia

PHYSICAL PROPERTIES : 

PHYSICAL PROPERTIES Fiber Diameter : 2 - 4 microns, Fiber Length : 100 - 250 mm, Fiber Shrinkage (1800 °F, 3h) : < 3.5% Working Temperature : 1800° F for Continuous Use, 2300° F Maximum Specific Heat: : 0.26 BTU/LB °F (@1,800 °F.) Overall Dimensions (Fabric Weight) : 101.7 gsm

PROPERTIES : 

PROPERTIES Thermal shock resistant Low elongation and shrinkage at operating temperatures Very low heat storage Excellent sound absorption Unaffected by water & steam Low thermal conductivity Asbestos free Resilient Light weight

APPLICATION : 

APPLICATION Ceramic Ropes , TAPES

Slide 10: 

Ceramic Fiber Filters Ballistic protection

KILN AND ACOUSTIC INSULATION : 

KILN AND ACOUSTIC INSULATION Al2O3 and SiO2 >97% (Al2O3: 47%), Fe2O3: < 1.1%

SOME MORE APPLICATION OF CERAMIC FIBERS : 

SOME MORE APPLICATION OF CERAMIC FIBERS Insulation of steam and gas turbines. Investment casting moulds. Reusable insulation for field stress relieving. steam generator (HRSG) silencers. process mufflers and sound walls. 782Fire protection and acoustic insulation at high temperatures High temperature pipe wrap

Conclusion : 

Conclusion Ceramic fiber is not a new fiber to the world of fibers but an innovative technology which is used in many fields which is getting an appraisal in the market it is still trying to bring about many changes in the field of composites , technical textiles and many more
