Ternary tellurite based glasses in the (TeO2)(ZnO)(TiO2) system were prepared and its optical properties and crystallization kinetics investigated by using UV‐VIS spectrophotometer and differential thermal analyzer (DTA). All the glasses were transparent from visible to near infrared region for different ZnO glass compositions (x=0.05, 0.10, 0.20, and 0.30 mol). In the experiment, optical band gap and Urbach energies were estimated from the optical absorption spectra between 400 and 800 nm wavelength region. The observed results confirm that the addition of ZnO glass composition from 0.05 to 0.30 mol increases the optical band gap energy from 2.94 to 3.0 eV. In addition, glass transition (Tg), crystallization (Tp) and melting temperature (Tm) were determined by using the DTA plots. Finally, DTA results obtained with a heating rate of 20°C/min show that the peak crystallization temperature increases from 463 to 533 °C as the ZnO content increases from 0.05 to 0.30 mol (© 2011 WILEY‐VCH Verlag GmbH & Co.

In the study, Al foams were produced using 6063 Al alloy casting dross and Boric acid. Foam materials were sintered at 130 ºC for 1 hour and at 550 ºC for 3 hours. The microstructure was analyzed with optical and scanning electron microscopes (SEM). Compression strength was measured with a compression tester. The porosity increased from 34.8% to 37.8%, the compressive strength increased from 12.43 MPa to 20.25 MPa, and the hardness increased from 98 HV to 115 HV with increasing dross amount.
