Material:Silver behenate

Silver behenate, or AgBH is silver salt of a long-chain fatty acid. It forms a lamellar-like structure with a repeat-spacing of ~5.8 nm.

It is frequently used as a calibration standard in SAXS and WAXS, because it generates a large number of well-defined rings whose q-position is well-known.
