In 1846–47, his brother and colleague-mineralogist Heinrich Rose found the major component of the mineral to be niobium and suggested altering the name to avoid confusion. The newly chosen name samarskite acknowledged the role of Samarsky-Bykhovets in granting access to the mineral samples. Later, several lanthanide elements were isolated from this mineral, and one of them, samarium, was named after the mineral, once again honoring Samarsky-Bykhovets.
