ZBLAN is a type of glass
that is made of a mixture of Zirconium, Barium, Lanthanum, Aluminum, and Sodium Fluorides. ZBLAN was discovered accidentally by Poulain and Lucas in 1975 at The University of Rennes, France. This material's main technological application is as an optical waveguide in planar and fibre form.

Although most of ZBLAN's properties (such as strength, thermal stability and corrosion resistance) are inferior compared to silica, ZBLAN transmits further into the infrared (IR) part of the electromagnetic spectrum and has a higher refractive index than most traditional glass formers. ZBLAN glasses have very poor resistance to attack by water and moisture. However, during melting these glasses 'self-dry'; any hydroxyl (-OH) groups in the glass network react with fluoride species in the glass, volatilising as gaseous hydrofluoric acid (HF).

ZBLAN is a variant which includes phosphorus.

The experiment must be largely automated so that human interaction
under the dicult conditions in micro gravity is not required.

Microgravity Processing of ZBLAN Optical Fiber

ZBLAN SamplesZrF4-BaF2-LaF3-AlF3-NaF (ZBLAN) is an infrared transmitting glass which can be made into optical fibers. ZBLAN has a theoretical attenuation coefficient of 0.002 dB/km which is 2 orders of magnitude better than fused silica. However, due to impurities and crystallites formed upon processing, ZBLAN subsequently has attenuation coefficients greater than 1 dB/km. Dr. Dennis Tucker along with researchers at MSFC and UAH has been studying the effects of gravity on the crystallization of ZBLAN. It has been found that processing ZBLAN in microgravity suppresses the crystallization and improves the transmission. Studies are ongoing to determine the crystallization mechanism on KC-135 flights.

Mechanical durability of ZBLAN and aluminum fluoride-based opticalfiber
Colaizzi, J.; Matthewson, M.J.
Lightwave Technology, Journal of
Volume 12, Issue 8, Aug 1994 Page(s):1317 - 1324
Digital Object Identifier 10.1109/50.317516
Summary:Zero stress aging and static fatigue experiments were performed on fluoride glass fibers of ZBLAN and aluminum fluoride-based compositions to examine the mechanical durability in aqueous solutions. ZBLAN fiber, which has the higher initial strength, becomes weaker than initially lower strength aluminum fluoride-based fiber in less than one hour in pH 7 buffer solution at 30°C. This is shown to be due to dissolution of the glass and precipitation of crystals at the glass/coating interface. In 1N NaOH the solubility is higher, resulting in less precipitation and hence less strength degradation. Although ZBLAN fiber degrades more quickly when a high strain is applied, at low applied strain the residual strength is higher than is observed when do strain is applied. These results indicate that future work on fluoride glass fibers for use in aqueous environments should focus on optimization of the as-drawn strength of durable glass, such as aluminum fluoride-based material, rather than on making small strength improvements to already strong but less durable glass, since such improvements will be quickly lost in aggressive environments
