Synthesis of MgTiO3 Powder Via Co-Precipitation Method and Investigation of Sintering Behavior

A co-precipitation method was used for synthesis of pure MgTiO3 ceramic powder with Mg(NO3)2.6H2O, TiCl4 or C12H28O4Ti and NaOH as raw materials. In this method, solutions of 1 M, Mg (NO3)2 6H2O and 2 M, NaOH were prepared. A stoichiometric amount of Ti precursors from TiCl4 or C12H28O4Ti was weighted. Solutions of Mg (NO3)2. 6H2O and Ti precursor were added dropwise to NaOH solution unde...

Synthesis of Hydroxyapatite Bio-Ceramic Powder by Hydrothermal Method

Hydroxyapatite bio-ceramic powder was synthesized using waste eggshells as calcium source by a straight forward thermal method. The process is carried out at high temperature. Different calcium phosphate phases were obtained just by changing the thermal treatment. HAp is the only apatite present in the reaction products, along with minute fractions of other calcium compounds. The final product ...

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Sintering properties of zirconia-based ceramic composite

This study examines the effects of different ZrB2 content on various mechanical properties and electrical conductivity of ZrB2/Y-TZP composite. Composites with ZrB2 content of up to 20 wt-% were particularly beneficial at the lower sintering temperature range by achieving greater densification and better hardness than Y-TZP monolith. In contrast to the trends estimated from rule of mixture, the...
