Magnesium orthosilicate (forsterite) whiskers were synthesized by an oxidation‐reduction reaction in the present investigation. These whiskers were rectangular parallelepipeds, with long sides in a cross‐sectional view from two to ten times as long as the short sides, and measuring from several micrometers to 200 μm wide and ∼15 mm in the elongated direction. The Mg 2 SiO 4 elongation was on the c‐axis. The growth mechanism of the whiskers was investigated on the basis of chemical thermodynamics, and the present study revealed that the Mg 2 SiO 4 whiskers grew by a VS (vapor‐solid) mechanism .
