Trans. Nonferrous Met. Soc. China 22(2012) 129-133 Effects of synthesis temperature and raw materials composition on preparation of β-Sialon based composites from fly ash MA Bei-yue, LI Ying, YAN... prepared from fly ash and carbon black under nitrogen atmosphere by carbothermal reduction-nitridation process. Effects of heating temperature and raw materials composition on synthesis process were......
Synthesis of steel slag ceramics: chemical composition and crystalline phases of raw materialsLi-hua Zhao1,2,Wei Wei1,2,Hao Bai1,2,Xu Zhang1,2,Da-qiang Cang1,21. School of Metallurgical...">Two types of porcelain tiles with steel slag as the main raw material(steel slag ceramics) were synthesized based on the CaO–Al2O3–SiO2 and CaO –MgO –SiO2 systems, and their bending strengths up......
J. Cent. South Univ. Technol. (2011) 18: 1924-1929 DOI: 10.1007/s11771-011-0924-y Influence of sulfur content in raw materials on oxidized pellets CHUN Tie-jun(春铁军), ZHU De-qing(朱德庆), PAN Jian(潘建... of sulfur content in raw materials on oxidized pellets was studied. The results show that most sulfur exists in the form of elementary sulfur in pyrite cinder, and over 95% sulfur is removed in producing......
oxide(B-MgO) after extracting Li2CO3 from salt lakes. We analyzed the elementary composition of the B-MgO raw materials and the effects of calcination temperature on the performance of MPBC. The phase composition and microstructure of the B-MgO raw materials and the hydration products(KMg PO4·6H2O) of MPBC were analyzed by X-ray diffraction and scanning electron microscopy. The results showed......
K for 9 h. It is shown that raw materials composition has an obvious effect on phase composition of the products. With the increase of carbon black content in sample, the diffraction peak intensities... the synthesis process, an important intermediate gas phase product is carbon monoxide. With the change of the raw materials composition (m(C)/m(ZrSiO4)), the reaction products maybe involve ZrO2, Si2N2O......
of the sorbents such as composition, water solubility, moisture content and density were measured according to ASTM standard methods. Also Fourier transform infrared spectroscopy (FTIR) of raw and acetylated.... Raw bagasse is a combination of cellulose, lignin, and hemicellulose. The composition was measured using standard methods in Table 3. Table 3 Raw sugarcane bagasse composition 2.3 Adsorption......
Preparation of Nano-Alumina with Aluminum Scraps as Raw Materials张良苗,冯永利,陆文聪,陈念贻摘 要:Ammonium aluminum carbonate hydroxide (AACH) was synthesized by the reaction of ammonium aluminum sulphate (AA) with ammonium hydrogen carbonate (AHC). AA was obtained by the reaction of NH4HSO4 with aluminum scraps as the raw materials. According to this method, AACH......
Influence of Characteristics of Alumina-silicate Raw Materials on the Formation Process of Clinker王亚丽,CUI Suping,LAN Mingzhang,TIAN Guiping,LIU LinglingSchool of Materials Science and Engineering, Beijing University of Technology摘 要:The traditional alumina-silicate raw materials, for example, clays, in the precalcining technique of cement production......
Composition and morphology of complicated copper oxalate powder FAN You-qi(樊友奇), ZHANG Chuan-fu(张传福), WU Jian-hui(邬建辉), ZHAN Jing(湛 菁), YANG Ping(杨 平) School of Metallurgical Science... by coordination- precipitation process with ammonium oxalate as precipitating agent. The composition and morphology of the powders were characterized by chemical analysis, X-ray diffraction (XRD), scanning electron......
composites were prepared by copper mold casting under the low vacuum with the argon atmosphere, and the raw materials used in preparing the Mg-Cu-Y-Zn alloys were commercially pure materials... stability of sample prepared with commercially pure raw materials is close to that of sample prepared with the high pure raw materials for the BMG Mg65+X(Cu0.66Y0.33)30-XZn5 (X=6). With the increase of Mg......
