Synthesis of Calcium Hexaboride Powder via Boro/Carbothermal Reduction with a Gel Precursor
(Goller Verlag GMBH, 2016)
In this study, the synthesis of calcium hexaboride powder via boro/carbothermal reduction (BCTR) using a single-step-processed gel product prepared from commercial boric acid, readily available and low-cost D(-)-Mannitol ...
Influence of cell aspect ratio on architecture and compressive strength of titanium foams
(Elsevier Science Sa, 2011)
Titanium foams have been of interest in dental and orthopedic implants over the past few decades on account of their excellent mechanical properties, chemical stability, and biocompatibility. A powerful tool, X-ray computed ...
Effect of Nano Hexagonal Boron Nitride Lubricant Additives on the Friction and Wear Properties of AISI 4140 Steel
(Taylor & Francis Inc, 2013)
The aim of this study was to investigate the effects of nano hexagonal boron nitride(hBN) particles on the friction and wear properties of AISI 4140 steel material when the hBN particles are used as an oil additive. Nano ...
Black ceramic pigments for porcelain tile bodies produced with chromite ores and iron oxide waste
(Korean Assoc Crystal Growth, Inc, 2011)
In this study, two different natural chromite ores and iron oxide waste from the steel rolling industry were used as less expensive alternative raw materials for the synthesis of black ceramic pigments to be used in porcelain ...
Fracture toughness of alumina/lanthanum titanate laminate composites with a weak interface
(Elsevier Science BV, 2007)
Layers of lanthanum titanate (La2Ti2O7) and alpha-alumina (alpha-Al2O3) were employed to form a layered composite in order to improve the fracture toughness of monolithic alumina. The composites were produced by two different ...
Processing of textured zinc oxide varistors via templated grain growth
(Elsevier Sci LTD, 2005)
Textured, dense zinc oxide varistors were successfully fabricated by Templated Grain Growth (TGG) technique. Rod-like, anisotropic ZnO particles (templates) were synthesized by homogeneous precipitation method. The templates ...
Investigation on the performance of SiAlON ceramic drills on aerospace grade CFRP composites
(Elsevier Science Sa, 2015)
Carbon fiber reinforced polymer (CFRP) composites are widely used in aircraft structure due to their outstanding physical and mechanical properties. Drilling is one of the most critical operation in the handling of CFRP ...
Oxidation behavior of electrically conductive alpha/beta SiAlON composites with segregated network of TiCN
(Elsevier Sci LTD, 2012)
The oxidation behavior of novel electrically conductive alpha/beta SiAlON composites with a continuous network of 2.5-10 vol% TiCN particulates was investigated. Composites, produced by coating spray dried granules with ...
The effect of the wet-milling process on sintering temperature and the amount of additive of SiAlON ceramics
(Elsevier Sci LTD, 2010)
In this study, nano-sized SiAlON powders were produced by wet milling at elevated speeds as a top-to-bottom process. Before the milling process, different milling times and mediums were performed for the determination of ...
Effect of transition metal oxide additions on the chemical durability of SrO-MgO-ZrO2-SiO2 glasses
(Soc Glass Technology, 2009)
SrO-MgO-ZrO2SiO2 quaternary glasses, such as 26SrO, 20MgO, 14ZrO(2),40SiO(2) (wt%,; Zrn glass) have been found to be highly alkaline resistant because of the high ZrO2 and MgO contents of such compositions, However, the ...
