Product Applications

Zircar Zirconia, Inc. manufactures a wide variety of oxide ceramic fibrous insulation with applications up to 2500 °C. With 40+ years in the industry we have served nearly every industry type for nearly every high temperature application.  Our insulation products stand up to the hottest, most corrosive environments providing solutions to your biggest challenges.

 

Ambient Temperatures

ZYP is yttria stabilized zirconium oxide powder. The nano-sized particles are used in industrial ceramic filtration membranes.  The unique shape and size distribution of the ZYP particles provide an excellent filtration media.

100 °C

Zirconia Cloth ZYK and ZYW are used as separators in aerospace nickel hydrogen batteries. The cloths are unaffected by chemical degradation and withstand 100 °C KOH indefinitely. The woven and knit structures promote electrolyte wicking and retention.  ZYK and ZYW should be evaluated for every electrochemical battery design.  To date Zircar’s ZYK has logged millions of separator- hours of space time – without any failures!

1600 °C

Buster A and Buster M Blankets are Zircar’s only product available in rolls for big insulation jobs where rigidity is not a requirement. Buster Blankets are useful as insulation packing.  In some Zircar hot zones Buster Blankets are used as part of modular furnace door designs.

Hot Spot 110L is our 110V lab furnace. It can reach 1600 °C in 30- 40 minutes and is the perfect furnace for your lab to calcine samples, measure shrinkage, or sinter small objects such as zirconia dental implants.

1650 °C

ZYZ and ZYC are yttria stabilized zirconia fibrous insulation that are bonded with silica. They have superior thermal shock resistance and are used to insulate molten metal transporting systems.

Buster A is an aluminum oxide fibrous insulation option with very low silica concentrations. It’s most useful in high vacuum and reducing atmosphere applications where silica cannot be tolerated, such as annealing furnaces with H2 atmospheres.  Buster A2-30 is used in some of Zircar’s hot zones where some applications are incompatible with silica.

1700 °C

Hot Spot 110 is a 110V lab furnace that has a smaller work zone than the 110L, but reaches 1700C for lab applications. It’s programmable controller with optional data output is useful in every materials research laboratory.

1800 °C

Buster M is an aluminum oxide fibrous insulation bound with silica forming a mullite bond. It has the ability to be precisely machined and is the choice for silica crystal manufacturers. Buster M has high electrical resistivity and can be in direct contact with resistance heating elements, such as it is in the Zircar HotSpot Lab Furnace, as hot face insulation and heating element holders.

ZYFB-3 is a yttria stabilized zirconium oxide fibrous insulation that has the lowest thermal conductivity (K) on the market, for applications above 1000 °C. It is used as a zone separator in directional solidification furnaces used to manufacture jet turbine blades and in fused quartz processing.

ZYFB-6 is also yttria stabilized zirconium oxide fibrous insulation with 60 pound per cubic foot (pcf) density. It is used as infrared source insulators in Fourier-Transform Infrared Spectrometers.

2000 °C

FBD is zirconium oxide fibrous insulation with 90 pcf density. It has been used as gasketing and insulation in high temperature wind tunnels, crystal growth stations, solar thermochemical reactors, oxygen/ carbon sensor protection sleeves, and has been used in nuclear meltdown experiments.

ZYF is useful up to 2000 °C as a separator, wrapper, fixture, gasket, cushion, pillow, pad, barrier, cover, layering or packing material. It is used in the Czochralski method of crystal growing as iridium and platinum crucible insulation and precious metal condensate reclamation material.

2200 °C

ZYK is zirconium oxide knit. It can withstand 2200 °C and is used as high energy separators, thermal insulation in crystal growing furnaces and for the filtration of hot gasses.

Y is yttrium oxide fibrous insulation that is available as bulk fiber, felts, knits, or cloths and is used as thermal insulation for high temperature microwave sintering and in the development of large grain rare earth barium copper oxide (REBCO) melt processed high temperature superconductors (HTS).

2400 °C

ZOG is high purity single crystal zirconia grog. It was developed for radio frequency (RF) induction furnaces operating above 2000 °C. ZOG is useful at temperatures up to 2400 °C under oxidizing conditions with no sintering or particle breakdown and minimal sticking.

2500 °C

ZO pure zirconia fibrous insulation in available as bulk fiber, felts, knits, or cloths and is used as insulation in very high temperature applications that are intolerant to yttria.

CE cerium oxide fibrous insulation is available as bulk fiber, felts, cloths, boards and pellets. It has use in electrochemical gasketing.  It has potential for use in a number of developmental applications such as redox flow batteries, solar syngas reactors, resistive- type oxygen sensors and fuel cells.  Cerium oxides have research attention as a promising material because of its utility as a catalyst. Ce4+ is reduced to Ce3+ and oxygen vacancies because of ceria’s high standard reduction potential.
