This study describes the role of in situ nano SiC whiskers on the strength and density of alumina silicate–SiC-carbonrefractory compounds. The prepared specimens were composed of 65 wt. % chamotte as alumina silicatecompound, 15 wt. % SiC-containing material regenerates and 10 wt. % fine coke and 10 wt. % liquid resole asbinder. Different values of additives (such as silicon a...

The aim of our research was to study how the conditions of immobilization influence cell attachment to two different ceramic surfaces: hydroxylapatite and chamotte tablets. Three fermentative yeast strains, namely brewery TT, B4 (ale, lager) and distillery Bc15a strains belonging to Saccharomyces spp., and one strain of Debaryomyces occidentalis Y500/5 of weak fermentative nature, but with high...

Geopolymers are generally appreciated for their good resistance against high temperatures. This paper compares the influence of thermal treatment with temperatures ranging from 200 to 1200 °C on the mechanical properties and microstructure of geopolymers based on two different aluminosilicate precursors, metakaolin and fly ash. Moreover, the paper is also aimed at characterizing the effect of c...

The adsorption behavior of aluminium ions on chamotte clay has been studied in this study. Chamotte used for the first time determination trace levels aqueous solutions. Quantitative and recovery were both rapid reached an equilibrium 30 minutes. Aluminium was detected based formation highly fluorescent Al(III)-morin complex. Two linear calibration graphs obtained range 0.5-10 µg L-1 10-100 wit...

Based on the analysis of published materials and new findings, archaeological complex Kiprinsky Borok has been given a general description, its various cultural chronological objects have identified, partially reflecting material culture population forest-steppe Altai from Neolithic to ethnographic modernity. The article presents characteristics fragments ceramic ware Early Iron Age Middle Ages...

the accumulative roll bonding process is used as a severe plastic deformation technique to produce aluminum composite sheets with ultra fine structure. in this study the effect of simultaneous use mg and sic particles as reinforcements, on the tensile properties of the al-mg-sic hybrid compositeis studied. the al-mg-sic hybrid composites with different amounts of mg and sic contents were fabric...
