“…The Brunauer-Emmet-Teller (BET) specific area of powdered perlite samples was measured using a Gemini® VII2390a analyzer at 77 K, under liquid nitrogen in Institute of Energy Technologies, Gebze Technical University, Gebze, Kocaeli, Türkiye. Before measurement, perlite samples were degassed under vacuum, at 120 °C for 2 hours (Kabra et al, 2013).…”

“…In this research, quantity-based definition instead of the style often encountered in literature that highlights the origin of country, (Roulia et al, 2006;Kabra et al, 2013) was chosen. Convenient way for defining perlite mineral could be expressing ranges of quantity of ingredients in XRF tests similar to Nasrollahzadeh et al work. Quantities was published in this paper by defining with the upper limit and lower limit.…”

“…Although these perlites look similar, mines could have differences in some aspects, as analysed with X-ray Fluorescence (XRF). Despite its industrial importance worldwide (www.perlite.org, 2022), only a few studies (Kabra et al, 2013;Celik et al, 2013) focused on the characterization of perlites.…”

Perlite is an amorphous volcanic glass-type rock which is collected in open mines in various parts of the world. In this study, eight different perlite samples, supplied from the mines located in the Bergama, Izmir region, were used. The perlite samples were structurally, morphologically, and mineralogically characterized via a wide range of analytical techniques such as Thermogravimetric Analysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR), Brunauer-Emmett-Teller (BET) Surface Area Analysis, Optical Microscopy, Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), X-ray Fluorescence (XRF), and a liquid pycnometer. Platelet shaped-like structures were observed in the SEM analysis of the expanded perlites in contrast to the images of spongy or cracked expanded perlites reported in literature. The O-H bending and Si-O-Si vibrations (both asymmetric and symmetric stretching) of perlite structures were confirmed by FTIR. Highly amorphous phases with a rather low percentage of crystalline phases were observed by XRD. In the BET surface area analysis, expanded perlite materials exhibited higher surface area compared to unexpanded ones. A detailed characterization of perlite structures is essential as there is a significant potential to use these minerals in various biocomposite applications and it is useful to explain structure-property relationships in this class of materials.

“…In the last few years, many farmers and gardeners have begun to use crushing products of igneous rocks including volcanic ash and other natural materials (namely as mineral nutrients) to supplement microelements and micronutrients in eroding and degraded soils (Fyfe et al, 2006, Alihosseini et al, 2010Kabra et al, 2013). When added to degraded soil, these minerals have a very clear effect on stimulating the growth and development of plants (Van Straaten, 2006).…”

As we know, vascular plants (Tracheophyta) in general and crop plants require a defined amount of trace elements to ensure normal growth and development. In many developed countries, some natural materials have been used as an addition for growing ornamental plants, vegetables, and hydroculture plants. In Vietnam, natural minerals to support plant growth is still very limited. Meanwhile, the source of raw materials in the territory of Vietnam is quite popular, so the research and experiments using Vietnamese volcanic ash and felsic volcanic rocks as improving materials for plant growing is important and very necessary work. Analytical methods such as Ronghen Fluorescence (XRF), Mass Spectrometry (ICP-MS), Scanning electron microscopy (SEM) and calcination at 6500C, 7500C, and 9000C have been used to determine the composition of felsic tuff samples belonging to the Don Duong Formation (PY19) and mafic ash samples of the Dai Nga Formation (KR2/2). In addition, control sample matching method was also used in the research process to evaluate the growth plants. The experiment materials (raw samples and calcined samples at 9000C) were mixed with the soil for planting (in different proportions); two types of plants, named Caviar Cockatio (Chicken Crest Vegetables) and Amaranth Asiatica (Purple Amaranth), were selected for experimenting. In general, both Caviar Cockatio and Amaranth Asiatica developed quicker when grew on a ground of soil mixed with the experiment material. The plant’s growth rate depends on the type of material (unbaked, calcined), support material content, plant type and stage of growth. Primary research results show that volcanic materials in Vietnam can support the growth of plants.
