“…Ogihara et al (1999) synthesized powders of barium titaniate to study the effect of temperature on the structure of the particles. According to Xia et al (2001), the conventional method of spray pyrolysis was only capable of producing sub-micron to micron sized particles. This limitation was overcome by adding salt to the precursor solution through ultrasonic aerosol decomposition in synthesizing single nanosize crystals of CeO 2 in the size range of 20-120 nm.…”

Silver particles less than 20 nm in diameter were synthesized by pyrolysis of an ultrasonically atomized spray of highly dilute aqueous silver nitrate solution at temperatures above 650• C and below the melting point of silver. Feed solution concentration and ultrasound power applied to the atomizer were found to have a significant impact on the particle size of the silver nanoparticles. Average particle size was found to be controllable in the range of 20 nm to 300 nm by varying the solution concentration and the ultrasound power to the atomizer.

“…The use of additional additives on the development of CSP method namely salt-assisted-SP (SASP) were reported in by Xia et al [33,34] and Panatarani et al [17]. On the other hand, reduced droplet size can be achieved either by using an electrospray which is capable of producing directly nanoscale monodispersed particles or by the modification of atomizing techniques, like filter expansion aerosol generator (FEAG) assisted spray pyrolysis (FEAG-SP) [35].…”

Abstract. Nanotechnology today is regarded as a revolutionary technology that can help to address the key needs related to energy, environment, health and agriculture in developing countries. This paper is a short review on the development and challenges of nanotechnology in Indonesia. Nanotechnology offers great potential benefits, there is emerging concerns arising from its novel physicochemical properties. The main applications of nanotechnology in the different sectors which is vital and its economic impact in Indonesia is also discussed. The achievment and development of nanotechnology including synthesis and dispersion of nanoparticles (NPs) and its applications in various fields is briefly addressed in Nanotehcnology and Graphene Research Center, Universitas Padjadjaran (Unpad). Despite significant progress in developmental goals, many challenges in the development of nanotechnology proccesing need to be resolved such as support infrastructure and evolution of new form of collaborative arrangements between various sectors and policies which is emerged as an important factor enabling development.

“…SaltAssisted Spray Pyrolysis (SASP) has been developed as a novel route to the prepara tion of nanoparticles (below 100 nm). 8) The presence of a salt in the precursor solution inhibits the agglomeration of nanocrystallites resulting in the formation of nonagglomer ated nanoparticles. This route requires no further thermal treatment of the product, such as calcination or annealing, because metal salts enhance both the homogeneity of the crystals and crystal growth.…”

The eects of salt concentration, operating temperature, and droplet/particle residence time in the hot zone as a function of carrier gas ow rate and heating zones on particle size, crystallinity, and chemical composition of BST nanoparticles were investigated. Highly crystalline, dense BST nanoparticles in a size range of 1760 nm with a narrow size distribution (s g 1.2) were prepared using a saltassisted spray pyrolysis (SASP) method without the need for postannealing or for controlling of initial excess of barium and strontium in the solution, relative to titanium. The particle size decreased with decreasing salt concentration, operating temperature and droplet/particle residence time in the hot zones. The chemical homogeneity of the resulting particles was analyzed using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICPAES). The chemical composition of the resulting powder completely reected the initial solution composition. SASP can be used to produce highly crystalline (Ba 1|x , Sr x )TiO 3 ( x0.5) nanoparti cles in sizes as small as 30 nm in a single step.
