TECHNICAL AND TECHNOLOGICAL ANALYSIS OF CERAMICS SINTASHTA OF THE KURGAN HALVAY 3

The article is devoted to technical and technological analysis of pottery sintashta kurgan Halvay 3. Kurgan Halvay 3 located on the left bank of the tobolsk sleeves Karatamar reservoir (Kostanay, north Kazakhstan), was investigated during the 2009-2010 field seasons of turgay archaeological expedition. diameter of 32 m including construction ditch embankment height of 1 m. Materials of the kurgan Halvay 3 belong to different archaeological periods, but the kurgan was built in sintashta era. there were investigated eighteen vessels from five wells sintashta (№1,3,6,8,9) and moat. technical and technological analysis of raw materials and ceramic molding compounds was carried out using the method of binocular microscopy and petrography analysis. the feedstock used ferruginated hydromica clay. For kneading the clay dough recipe used two molding composition: clay +gravel + gruss manure; clay + gravel. among technological methods in the manufacture of vessels recorded the use of bottom-capacitive, capacitive starting, spiral zone, lumpy patchwork, flaps, harnesses and pattern. ceramics of the kurgan Halvay 3 (recipes molding compounds, processing methods in the manufacture of vessels) is directly analogous to those sintashta monuments of the southern Urals as settlement arkaim, Ustie and burial Bolshekaragansky.

Manufacture of Electrolyte Component of SOFC

The manufacture of the electrolyte film is crucial for the fabrication of solid oxide fuel cells (SOFCs). This paper reviews the main methods for fabricating the electrolyte film, which are generally classified as chemical methods, physical methods and ceramic molding methods. The characteristics of each method and its application are discussed.
