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...

Nanocrystallite α-cordierite glass-ceramics are synthesized using a modified Pechini method. The structural and lattice modes of the products are investigated via XRD and Micro Raman back-scattering spectroscopy. The Debye-Scherrer formula is used to confirm the grain sizes estimated by the SEM slides. Dielectric coefficients calculation and DTA analysis are used to study the synthesized nanocr...

Metamorphic area, which is a subject of this study, is located in S-Qorveh (Zarineh region), northwest of the Sanadaj-Sirjan zone. According to the recent dating, the S-Qorveh plutonic body consists of a complex of granitoids, granodiorites, quartz monzonites, and gabbros, have intruded into the host metamorphic rocks, about 149-152 Ma and have generated contact metamorphism. Intrusions of vari...
