The following statement is correct: (a) The outermost electron numbers of boron atom (b) and nitrogen atom (n) are 3 and 5 respectively, and they react to form high-temperature superalloys.

A, the outermost electron number of boron atom is 3, and it is easy to remove 3 electrons in chemical reaction, showing +3 valence, while the outermost electron number of nitrogen atom is 5, and it is easy to get 3 electrons in chemical reaction, showing -3 valence, so the chemical formula of high temperature superconducting materials formed by their reaction is very likely BN, so the statement is wrong;

B, some catalysts can slow down the reaction speed, so it is wrong;

C. In the process of incandescent lighting, only electric energy is converted into light energy and heat energy, and no new substances are produced, which belongs to physical changes, so the statement is wrong;

D. The chemical properties of carbon in ink are very stable at room temperature, so China's calligraphy works will not fade for a long time, so the statement is correct;

So choose D.
