On the basis of microstructural evidence it is clear that SMC metapelites have experienced at least two regional (RM1, RM2) and one contact metamorphism (CM). During RM2, several porphyroblasts including kyanite, andalusite, staurolite, cordierite, garnet and fibrous sillimanite have grown in the mica - schists. In order to estimate the PT condition of metamorphism of metapelites, we used catio...
A modified Scheffe's simplex lattice design method is proposed to study the properties of multicomponent materials. This allowed determining optimal compositions cordierite and corundum based ceramic materials that are used as catalyst carrier for gas purification equipment. The obtained material (0.63-1.25 mm weight fraction 0.35 mass% fraction; < 0.63 0.06 0.2 1.25-2.5 fraction) was succes...
The aim of the presented research was to analyze ceramic material based on cordierite as a function activation time and sintering temperature. Three-component oxide mixture prepared (MgO + Al2O3 SiO2 in ratio 2:2:5). To decrease temperature, 10 mass % Bi2O3 added this mixture. mixtures were mechanically activated for 5 240 minutes ball mill. Activated sintered at temperatures 1173-1573K. XRD me...
