Measurements of rates of dissolution of typical insulation wool fibers (glasswool and basalt based stonewool) and an experimental fiber were made using a flow-through equipment. The liquids used were a modified Gamble's solution, adjusted to pH 4.8 and 7.7 +/- 0.2, respectively. The dissolution of SiO2 and CaO was determined over periods of up to three months. The rate of dissolution of stonewo...

Chemical vapor deposition (CVD) is used as a method for the synthesis of carbon nanotubes (CNT) on substrates, most commonly pre-treated by a metal-catalyst. In this work, the capability of basalt fiber surfaces was investigated in order to stimulate catalyst-free growth of carbon nanotubes. We have carried out CVD experiments on unsized, sized, and NaOH-treated basalt fibers modified by growth...

The paper considers the use of basalt ore - natural raw materials volcanic origin in Uzbekistan, as well wide fibers various sectors economy and their further prospects. Basalt rocks are for production ultrafine fibers, belong to magmatic possess high chemical thermal stability. single-component that have been enriched, melted homogenized by ancient activity. However, main energy input primary ...

Basalt fiber is a low cost materiel obtained from the rock earth, and it can be divided into small pieces to form fiber. In this paper dealing with manufacturing, property of composites application are reviewed. The results indicate that as compared glass fibers, carbon fibers armide fiber, basalt possesses excellent machine driven properties such wave permeability, electrical properties, non-c...

Fiber length and persistence are thought to be determinants for the development of toxic, fibrogenic, and carcinogenic effects of fibrous dusts. When the solubilities of chrysotile asbestos (CA) and basalt fibers (BF) were compared by measuring the loss of silica and magnesium in Leineweber's solution, CA was shown to be the more soluble. In a 6-month inhalation experiment, chrysotile at a mean...
