中国耐火材料（英文版）/Journal China's Refractories
查看更多>>本刊1992年经国家科委批准创办,由洛阳耐火材料研究院主办,是目前中国耐火材料行业唯一的一本英文杂志,现为季刊。创刊以来己出11卷(包括今年),受到海内外学者、企业家、商人的欢迎。目前与国外二十家杂志建立了交换关系,例如,美国的"陶瓷协会会刊与英国的"耐火材料与陶瓷",德国的"陶瓷论坛",比利时的"硅酸盐",法国的"陶瓷工业",日本的"耐火物"等。并且与几家著名的二次文献检索刊物也建立了密切联系。 目前国内外订户及赠阅数、交换数达1000多本/年,国外订户主要分布在美国、英国、印度、日本、德国、法国、南非、阿根廷以及东南亚和阿拉伯等十几个国家。 本杂志主要反映当前中国耐火材料发展现状。论文内容涉及到原料、工艺、生产及应用方面的新进展,以及设备更新。除研究报告和论文、综述与展望外,还报道了国家公布的一些统计数据,市场信息反迸出口情况等。同时我刊还可刊登广告和厂矿简介。 当时创办该刊的目的主要是让世界了解中国耐火材料,试图在中国耐火材料与世界耐火材料同行之间架起一座信息桥梁。尤其中国已加入世界贸易组织(WTO),我们需要更多地参与国际市场竞争,那么通过《中国耐火材料》的介绍,无疑是一条重要的渠道。 目前为止,由于《中国耐火材料》的介绍或通过《中国耐火材料》的报道,取得与国外商人联系并最终出口耐火材料产品或原料的企业十几家。 众所周知,中国耐火材料通过20多年改革开放,无论在原材料的质量上还是在制成品的质量上都有了长足的进展,有的已接近或超过国外先进水平。由于过去政策封闭,耐火材料行业因与外界联系较少,出口渠道少,出口最也就少。随着我国改革开放政策的深入,与国际同行交流日趋增加,中国耐火材料原料及产品出口也逐年增加,但与中国耐火材料产量相比,远远不够.尤其在国内市场竞争日趋激烈的条件下,寻求出口不乏是重要出路之一。因此需要更多媒体的介入,以便广交国际朋友,扩大出口渠道。

    查看更多>>摘要：To address the issues of reduced performance and shortened lifespan during the low-carbonizating process of Al2O3-C refractories,nano-crystalline ZrC modified graphite was prepared using Zr powder and flake graphite as raw materials,with NaCl and NaF mixed salt serving as the medium.The flake graphite was gradually replaced by ZrC modified graphite in the preparation of Al2O3-C refractories,and its impact on the material's structure and properties was investigated.The results indicate that,compared to samples with only flake graphite,the introduction of 1 mass％to 5 mass％ nano-crystalline ZrC modified graphite can significantly enhance the mechanical performance of low-carbon Al2O3-C refractories.When 5 mass％ZrC modified graphite is added,the mechanical properties of the samples are optimal,with the cold modulus of rupture and elastic modulus reaching 22.5 MPa and 65.0 GPa,respectively.

    查看更多>>摘要：To optimize their Al2O3-SiO2 raw materials,anorthite based insulation refractories were prepared by the in-situ sintering process combined with the foaming method after sintering at 1 350 ℃ for 3 h,using green and pollution-free kaolin,kyanite,andalusite and sillimanite as Al2O3-SiO2 raw materials,respectively,and industrial CaCO3 as the CaO source.Effects of Al2O3-SiO2 raw material types on the physical properties,phase composition and microstructure were investigated.The results are as follows.All samples prepared by different Al2O3-SiO2 raw materials have hexagonal flake anorthite and a small amount of mullite and corundum.Their bulk density and thermal conductivity decrease in the order of using kaolin,andalusite,kyanite and sillimanite as the Al2O3-SiO2 raw material,but their apparent porosity increases.Moreover,in the sample with kaolin,the bonding between anorthite crystals on the pore walls is closer than that of the other samples,which is conducive to increasing the cold crushing strength.The bonding between anorthite crystals on pore walls gradually decreases in the order of using kyanite,andalusite and sillimanite as the Al2O3-SiO2 raw material,thus their cold crushing strength decreases accordingly.In comprehensive consideration,the properties of the sample from kyanite are the optimal.Its apparent porosity,thermal conductivity and cold crushing strength are 84.6％,0.141 W·m-1·K-1 and 1.89 MPa,respectively.

    Effect of CaO Impurity on Mullite Formation from SiO2 Gel and Al2O3 Powders

    34-39页
    查看更多>>摘要：To broaden the application of SiO2 sol-bonded castables,using micro-or nano-Al2O3 powder and SiO2 gel powder as the main raw materials,the effects of CaO impurity on the formation of mullite by the reaction of Al2O3 and SiO2 at different temperatures(1 350,1 400,1 500,and 1 600 ℃)in different atmospheres(oxidation atmosphere and reduction atmosphere)were studied.The results show that in the oxidizing atmosphere,the introduction of CaO can promote the formation of mullite.When the temperature increases from 1 350 ℃ to 1 600 ℃,the amount of mullite formed gradually increases.In the reducing atmosphere,the introduction of CaO is not conducive to the formation of mullite,and the amount of mullite decreases with the increasing temperature.The smaller the particle size of Al2O3,the more easily it reacts with SiO2 gel powder to form mullite.

    查看更多>>摘要：Fiber products for microwave kilns were prepared using alumina fibers with alumina contents of 72 mass％and 80 mass％,and calcined alumina powder(4-6 μm)as the main raw materials,silica sol as the binder,and cationic starch as the flocculant.Effects of different raw materials and their additions on the wave transparency of fiber products were researched.The results show that as the alumina fiber(72％)addition increases,the heating rate of the samples first decreases and then increases,and the corresponding wave transparency of the sample first increases and then decreases.When the alumina fibers addition is 40 mass％and the alumina powder addition is 30 mass％,the prepared microwave kiln lining material has a higher mullite content,which improves the wave transparency of the sample.The sample prepared from alumina fibers with an alumina content of 80％has a suitable glass-mullite phase ratio,performs lower overall dielectric constant and good wave transparency,and is a suitable lining material for microwave kilns.

    44-48页
    查看更多>>摘要：Aiming at improving the properties of magnesia carbon materials,silicon aluminum carbide(Al4SiC4)containing materials were prepared using industrial aluminum powder,silicon carbide powder,and graphite as raw materials,and activated alumina powder as an additive,mixing thoroughly,pressing into cylinders and then firing at 1 200 ℃ for 30 min in a carbon embedded atmosphere by the microwave method.The effects of the aluminum powder addition(20％and 24％,by mass)and activated alumina powder addition(0,3％,5％and 7％,by mass)on the microwave synthesis of Al4SiC4 as well as the effect of the obtained Al4SiC4 containing material on the properties of magnesia carbon bricks were studied.The results show that:compared with the samples with 20％aluminum powder,those with 24％aluminum powder generate more Al4SiC4.With the activated alumina powder addition increasing from 0 to 7％,the amount of Al4SiC4 generated increases first and then decreases.Compared with the sample without activated alumina powder,the samples with activated alumina powder show lower bulk density and higher apparent porosity.With the activated alumina powder addition increasing from 3％to 7％,the bulk density of the samples increases first and then decreases,while the apparent porosity of the samples shows an opposite trend.The optimal additions are 24％aluminum powder and 5％activated alumina powder,and Al4SiC4 synthesized in this sample has a hexagonal plate structure.With the synthesized Al4SiC4 containing material added,the magnesia carbon brick has slightly increased cold modulus of rupture,basically the same modulus of elasticity and improved oxidation resistance.
