Specialty Fibers
With ACI’s viscose suspension spinning process (VSSP), nearly any ceramic material including oxides and ferrites can be spun into fiber.
Spun Ceramic Fibers – sintered or green ceramic fibers of over 60 chemistries are produced today.
- 15-250 micron diameters
- To any specified length
- Chemistries include (but are not limited to): bioceramics and structural ceramics such as alumina, yttria stabilized zirconia, silicon carbide, silicon nitride, and sialon
Current spun chemistries include:
- PZT for energy harvesting, sensing and actuation
- YAG fiber for very high temperature composite reinforcement
- SiC fiber for reinforcement of silicon carbide armor
- Hydroxyapatite fiber for reinforcement of synthetic bone, teeth and many more.
- Carbonizable rayon for rocket nozzles
- TiO2
- Alumina
- Zirconia
- Silica
High Purity Ceramic Fibers
Yttria Stabilized Zirconium Oxide Fibers
- Diameter ranges from 15-250 microns
- Made using TOSOH's 3Y or 8Y powder or as specified
- Very low silica content
- Very flexible after sintering
- Much less expensive than high purity YTZ fibers
- Use as fuel cell separators, and CMC structural reinforcement
Electrically Conductive Fibers
- ACI's patented conduxite material
- Diameter range 15-250 micron
- Resistance range from 3x10-5 ohm-cm to 1x10-1 ohm-cm
- Chemically resistant
- Use as battery electrode support to increase life and conductivity
- Make conductive plastic
- Make electrostatic precipitator grids
Examples of Other Ceramic Fibers
- Yttrium aluminum garnet fibers
Excellent as a high temperature composite reinforcement
- Lithium aluminate fibers
Fuel cell applications
- Low loss/high dielectric fibers
Used in microwave applications
- Iron silicide
For stealth applications
- Zirconium diboride
Used in very high temperature composites
ACI can make fibers from almost any powdered material using its patented VSSP fiber spinning process. Please contact ACI, if you are interested in having your material to be evaluated for fiber production.
