Abstract. This paper reports on phase formation and microstructural development of mullite, derived from B 2 O 3Al 2 O 3SiO 2 mixtures activated with different milling methods. It is found that the addition of B 2 O 3 has a positive effect on mullite phase formation from the mixture of Al 2 O 3SiO 2, which can be qualitatively attributed to the fact that B 2 O 3 brought out higher
