Abstract

This study is introducing a facile and novel method for synthesis of amorphous silica nanoparticles. Silica nanoparticles were synthesized by pyrolysis and combustion of high temperature vulcanization (HTV) silicone at 700 oC for 1 h. The products were investigated employing transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), dynamic light scattering (DLS), X-ray diffraction (XRD), Brunauer Emmett and Teller (BET) test and Fourier Transform Infrared (FTIR) Spectroscopy. The results indicated that the method is capable of synthesis of amorphous silica nanoparticles with sizes of mostly between 10 and 50 nm.

Highlights

Demand for nanoparticles is growing with advance of science and technology.These nanoparticles are used in several areas such as optoelectronics, catalysis, micro electronics, information storage, etc. [1,2,3]
thermogravimetric analysis (TGA) revealed that pyrolysis of high temperature vulcanization (HTV) silicone was taken in the temperature range of 500–650 C
Silica nanoparticles were produced by pyrolysis and combustion of HTV silicone at 700 °C for 1 h, including heating up time from ambient temperature at heating rate of 20 °C/min

Summary

Introduction

Demand for nanoparticles is growing with advance of science and technology.These nanoparticles are used in several areas such as optoelectronics, catalysis, micro electronics, information storage, etc. [1,2,3]. Production of silica nanoparticles for use in catalysts, semiconductors, thermal insulators, glass, ceramic and concrete is taken into consideration in the last decade [4,5,6,7,8]. They are used as drug carriers in pharmaceutical industry due to their large specific surface and high biocompatibility [9, 10]. Silica nanoparticles are often produced using chemical methods such as sol-gel and deposition [15,16,17,18,19]. It has disadvantages such as long drying times, high shrink age and difficulty in preparing non-oxide ceramics [20]
