Hi,

I'm looking for a library of spectral reflectance data of ceramic and
other materials. Especially I'm interested in Al2O3, TiO2, AlTiO2,
ZrO2, Si3N4, SiC. The reflectance data should cover the range from
visible light (0.4 µm) up to 4 µm. A reduced range up to 3 µm is
acceptable. Reflectance data should be available for at least 30
different materials.

I already found a spectral library for minerals etc. at
http://speclab.cr.usgs.gov/spectral.lib04/spectral-lib.desc+plots.html,
however I was unable to find something similar for the materials
mentioned above.

Hello engineer5555-ga

I have found a spectral library of more than 2000 items. It includes 
Minerals, Rocks, Soils, ... Vegetation ... Man Made etc. The spectra
cover range goes from 0.4 to 25 micrometers. I could find brick,
paint, concrete, terra cotta tiles but not ceramic tiles. Would you be
interested ?

Hello  silviares-ga,

thank you for your looking into this. Unfortunately, I really need
data from ceramic materials I mentioned (Al2O3, TiO2, AlTiO2, ZrO2,
Si3N4, SiC).

Best regards

A couple of those are in the table that you found:

Al2O3 = Corundum
TiO2 = Rutile

The National Institute of Standards and Technology has a new data base
that might be helpful.
