Opis:: Mica glass-ceramic was prepared by sintering method from in the $SiO_2-Al_2O_3-MgO-K_2O-B_2O_3-F_2$ system. The sintering behavior and machinability of a glass-ceramic composition were examined. The starting materials were mixed and milled in an alumina ball mill for 2 h. Then the powders were sieved to obtain grain sizes smaller than 75 μm. For the shaping process, disc samples were prepared by pressing at 100 MPa. The pressed discs were sintered at temperatures in the range from 900 to 1200C for 2 h in an electric furnace using a heating rate of 5°C/min. X-ray diffraction analysis, scanning electron microscopy, and machinability tests for characterization were performed on sintered samples. The results showed that all samples exhibited similar phases formation and good machinability.

Opis:: Glass-ceramics were produced by sintering method from industrial waste materials such as fly ash, blast furnace slag and boron waste. The sintering behavior and machinability of glass-ceramic compositions were investigated. Additives were added to waste materials for enhancement of machinability and sintering properties. All starting materials were mixed by ball milling for 2 h using alumina media. The mixed and milled powders were sieved to grain sizes smaller than 75 μm and pressed at 100 MPa. The pressed samples were sintered at 900°C, 1000°C and 1100°C for 1 h in an electric furnace using a heating rate of 5°C/min. Some characterization tests such as X-ray diffraction (XRD), scanning electron microscopy (SEM) and machinability tests were performed on sintered samples. The results indicated that all samples exhibit good sintering and machinability properties.

Opis:: In this study, the effects of perlite addition on mechanical properties and wear resistance of alumina ceramics were investigated. Alumina powders including perlite 5%, 10%, 15%, 20% and perlite free were prepared. These powders were shaped as rectangular by using uniaxial pressing system under the load of 100 MPa. The samples were sintered at 1400°C-1550C for 2 h and were subjected to some mechanical tests such as hardness and fracture toughness. X-ray diffraction analysis was employed to determine the crystalline phases. Bulk densities of the samples were measured. In addition, erosive wear test was performed to investigate the erosive wear resistance of the samples. The wear test results were presented depending on different sliding speed and sintering temperature. These results showed that perlite addition has a positive effect on erosive wear resistance of the alumina ceramics, generally.
