A nanosphere-like zinc borate 4ZnO·B2O3·H2O was successfully synthesised through homogeneous precipitation reaction, with hexadecyl trimethyl ammonium bromide as the surfactant. X-ray diffractometer, Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, transmission electron microscopy were utilised to characterise the samples. These crystal products demonstrated spherical morphology with about 50–100 nm particle size. Moreover, the effect of initial pH combined with concentration of raw materials was briefly studied. The effect of char promotion of nanosphere-like zinc borate 4ZnO·B2O3·H2O in polystyrene as flame retardant was also revealed via the pilot study.
