β¦ Synopsis
A novel and general processing (heterogeneous nucleation and growth processing) was used to prepare composite coating particles with homogeneous component distribution. Composite coating particles consisting of Ξ±βAl~2~O~3~ cores with an outer amorphous silica layer were prepared by this processing using an ethanol suspension containing ammonia, tetraethylorthosilicate and Ξ±βAl~2~O~3~. Fine mullite powders (d~50~ = 0.73 ΞΌm) were fabricated by calcinating these particles at 1500 Β°C for 2 h.

## Abstract **Summary:** It is well known that poly(propylene)/clay (PP/clay) nanocomposite forms an exfoliated structure when mixed with maleic anhydrideβfunctionalized polypropylene (MAPP). This can be easily achieved by melt processing, however, the use of functionalized chemicals like MAPP cost
