Oxidation of Ca-α-SiAlON Powders Prepared by Combustion Synthesis
The oxidation of Ca-α-SiAlON synthesized by the combustion synthesis (CS) method with different additives was investigated in air atmosphere using thermogravimetric (TG) analysis in a temperature range from 1453 K to 1653 K. The experimental results indicated that oxidation was controlled by mixed chemical and diffusion steps. The oxidation products by XRD analysis were composed of SiO₂ and CaA...
متن کاملMechanically Activated Combustion Synthesis of B4C-TiB2 Nanocomposite Powder
Boron carbide is one of the hardest materials. The combustion method was used to synthesize B4C-TiB2 nanocomposite powder in a B2O3-Mg-TiO2-C system. An experimental study of the formation of B4C–TiB2 nanoparticles was conducted in the thermal explosion mode. A mixture of B2O3:TiO2:Mg:C at a molecular ratio of 3:1:12:1 was chosen to obtain the B4C–TiB2. This powder mixture was milled for differ...

متن کاملEffect of Seeding on the Microstructure and Mechanical Properties of alpha-SiAlON: II, Ca-alpha-SiAlON
Seeding effects on the microstructure and mechanical properties of single-phase Ca-α-SiAlON ceramics have been investigated. Whereas a small amount of seeds can transform the microstructure from one of fine equiaxed grains to one consisting of many needle-like grains, the highest fracture toughness of 8 MPa . m1/2 is not reached until 8% seeding. This contrasts with the much higher seed efficie...
متن کاملSynthesis of TiC-Al2O3 Nanocomposite from Impure TiO2 by Mechanical Activated Sintering
In this research, the production possibility of TiC-Al2O3 nanocomposite, as a useful ceramic from commercially pure TiO2, aluminum powder and carbon black has been investigated. Routile (TiO2) with carbon black and aluminum were placed in a high energy ball mill and sampled during different milling times. Then, the activated powders were synthesized at different temperatures in an atmosphere co...
