Mullite whiskers were synthesized by a vapor-solid reaction with $Al(OH)_3-SiO_2-AlF_3$. The heat treatment temperature did not affect the shape of mullite whisker but the composition change resulted in different sizes. The first one was $30-50{mu}m$ in size with the aspect ratio of 60 and above, and the second one was $600{mu}m$ and below in size with the aspect ratio of 15 and below. The $Al_2O_3$ content in formed mullite whisker was 73.57-80.29 wt%, which is high $Al_2O_3$ content composition. The Young's modulus and the hardness measured by nano-indentation method were 136.7 GPa and 19.81 GPa, respectively.
Key words: Mullite whiskers, Vapor-solid reaction, Nano-indentation
