·Ternary master slags based on the CaO Al2O3 SiO2 system with CaO/SiO2 C/S ratio were doped with 5 20 wt pct of anhydrous borax Na2B4O7 to study the phase equilibria of the quinary CaO Al2O3 SiO2 Na2O B2O3 slag system within the temperature range 1050 1350 °C This research uses the well known method of high temperature
·Sample A and C were the CaO SiO 2 and CaO SiO 2 Al 2 O 3 slag systems respectively Sample B and D were designed to study the influence of CaF 2 on the sintering behavior of CaO SiO 2 slag and CaO SiO 2 Al 2 O 3 slag respectively The prepared powder samples were mixed well using the Electromagnetic ore crusher
·¿Qu es el óxido de calcio El óxido de calcio CaO es un compuesto inorgánico que contiene calcio y oxígeno en formas iónicas no confundir con el peróxido de calcio CaO 2 Mundialmente se le conoce como cal palabra que designa a todo compuesto inorgánico que contiene carbonatos óxidos e hidróxidos de calcio además de otros metales
·With the raw materials for ironmaking are becoming increasingly complex more accurate control of blast furnace operation is essential to reduce the energy cost and CO2 emission CaO SiO2 Al2O3 MgO is a basic system of ironmaking slag in which CaO and MgO are mainly come from the flux SiO2 and Al2O3 are mainly from the raw materials Effect of
·The hydration resistance of CaO materials prepared by Ca OH 2 calcination with chelating compounds are investigated in this paper The crystalline phases and microstructure characteristics of sintered specimens were studied by X ray diffraction XRD X ray photoelectron spectroscopy XPS scanning electron microscopy and energy dispersive
·In the comprehensive development and utilization of crop straw it is key to separate the fibers in the straw through a certain process or equipment In order to obtain rice straw fiber material the straw fiber crusher was designed using SOLIDWORKS software and its grinding process was simulated using EDEM software to verify the feasibility of the machine
·The calcium looping energy storage is a promising technique for thermochemical energy storage in concentrated solar power plants Nevertheless natural CaO based materials such as limestone have an obvious decline in energy storage capacity during cyclic CaO/CaCO 3 energy storage In this work a novel Al 2 O 3 /CeO 2 co doped CaO based material for energy
·Download Citation Material flow in jaw crusher Jaw crusher is a kind of machine widely used in mining and aggregates industry but it still has some shortcomings such as liners wear terrible
·Detailed understanding of the mechanisms of the fast stage during CaO carbonation is important for the design of novel efficient CaO materials This work systematically studies the formation of a CaCO 3 product layer on the outside surface of CaO grains during the fast reaction stage for carbon capture using two types of CaO adsorbents
·Ghosh et al [18] studied the influence of the addition of CuO on the sintering properties of CaO materials the results showed that the bulk density of the CaO with wt% CuO possessed 93% of the theoretical density after sintered at 1550 °C because the formation of a low melting phase 2 CuO·CaO contributed to the improvement on the

·MgO CaO refractories were prepared using analytical reagent chemicals of Ca OH 2 and Mg OH 2 as starting materials and CeO2 as dopant then sintered at 1650°C for 3 h The effect of CeO2 powders on the defect of MgO CaO refractories was investigated The sample characterizations were analyzed by the techniques of XRD and SEM According to the
·For CaO based materials it is widely believed that the performance decay is caused by macro pore plugging and loss of meso porosity induced by sintering [29 30 54] corresponding to the disappearance of pore structures and growth and particles For CaMn91 sintering occurred after 15 cycles and it became more severe after 25 cycles
·Materials and Methods CaO was obtained by heating CaCO 3 Aladdin pct at 1223 K in air for 6 hours followed by milling and sieving to select particles smaller than mm CaCl 2 Macklin pct was subjected to vacuum heating at 473 K for 72 hours and subsequently heated to 773 K in Ar for 12 hours to remove moisture before the dissolution
·To moderate the erosion in a slag line zone and extend the service life of a submerged entry nozzle during continuous casting of high Mn and high Al steel the current study developed a low reaction CaO Al2O3 based slag with lower SiO2 and higher Al2O3 contents than that of conventional CaO SiO2 based slag The static sessile drop technique and dynamic
