3Sintering Densification of Boron Carbide Materials and Their Research Progress显示文摘Boron carbide(B_(4)C)has excellent high-temperature oxidation resistance,high hardness,low relative density,high melting point and excellent abrasive resistance,which is widely used in fields such as refractories,wear-resistant materials and lightweight protective materials.The research progress and application of B_(4)C materials in China and overseas in recent years were summarized.The influences of sintering processes(pressureless sintering,hot-pressing sintering,hot isostatic pressing sintering,spark plasma sintering and microwave sintering)and sintering additives(simple substances,oxides and carbides)on the B_(4)C densification were analyzed.The development of B_(4)C materials was prospected.ZOU Xin CHEN Ping'an XU Guangping LI Xiangcheng ZHU Yingli ZHU Boquan 2023China's Refractories2023,32,4:0
4燃烧合成C/MgAl_(2)O_(4)复合粉及其显微结构演变显示文摘为解决纳米碳在应用过程中难分散、易氧化、成本高等问题,以草酸镁(MgC_(2)O_(4))、过氧化镁、Al_(2)O_(3)粉和Al粉为原料,燃烧合成碳/镁铝尖晶石(C/MgAl_(2)O_(4))复合粉。结果表明,当MgC 2O 4的最大掺量是33.34%(w)时,C/MgAl_(2)O_(4)复合粉中碳含量为1.17%(w),碳夹杂于尖晶石晶粒间。复合粉中镁铝尖晶石具有粒状及棒状两种形貌。粒状镁铝尖晶石由MgO与Al_(2)O_(3)相互扩散形成,棒状镁铝尖晶石由Mg蒸气与原料Al_(2)O_(3)以气-固生长机制主导形成。吕李华 丁冬海 肖国庆 2021耐火材料2021,55,5:0
5Combustion Synthesis of C/MgAl_(2)O_(4)Composite Powders and Their Microstructure Evolution显示文摘This work aims at solving the problems of difficult dispersion,easy oxidation and high cost of nano carbon during application,carbon/magnesium aluminate spinel(C/MgAl_(2)O_(4))composite powders were prepared using MgC2O4·2H2O,MgO2,Al2O3 powder,and Al powder as raw materials by combustion synthesis.The results indicate that with the maximum MgC2O4·2H2O addition of 33.34 mass%,the prepared powder contains 1.17 mass%of carbon and carbon distributes among spinel grains.The MgAl_(2)O_(4)spinel shows both granular and rod-like morphologies.The granular MgAl_(2)O_(4)spinel is generated from mutual diffusion between MgO and Al2O3;while the rod-like MgAl_(2)O_(4)spinel is mainly formed by the vapor-solid growth mechanism from Mg vapor and Al2O3.LYU Lihua DING Donghai XIAO Guoqing 2021China's Refractories2021,30,4:0
