Molten salt synthesis of mullite whiskers from various alumina precursors

Preparation and characterization of mullite whiskers from silica fume by using a low temperature molten salt method

“…The broad endothermic peak in our experiment is similar to that reported in Ref. [10]. One a slight difference in peak position is observed, which could be due to the fact that our silica fume is in nanometer scale.…”

Template free synthesis of highly ordered mullite nanowhiskers with exceptional photoluminescence

“…Ultrafine silica was added in the system. To investigate the effect of Al/Si, the ratio of Al:Si was settled as 3:1 and 2:1 [15]. B 2 O 3 is a common agent to decrease the viscosity and surface tension of the flux [18].…”

“…Among these methods, MSS is an efficient one because it can not only decrease the reaction temperature but also control the morphology of the product [11,13]. It has been reported that mullite nanowires are synthesized using MSS [12,[14][15][16]. However the morphology of the synthesized mullite nanowires using this method is disordered, which is difficult to make full use of the nanoscale material.…”

Mullite whiskers prepared by molten salt method using Si powders

“…As a new ceramic powder synthesis method, molten salt synthesis has been employed to synthesize ceramic powders because it decreases reaction temperature and gives powders of homogeneous morphology [8]. Mullite whiskers formation in molten salts system has been extensively studied [9][10][11][12][13]. But earlier studies focused on utilizing SiO 2 as raw material, there was no report about the preparation of mullite whiskers from Si powders by molten salt synthesis.…”
