摘要

采用最佳的氧化镁（MgO）与硼酸（H3BO3）的摩尔比，通过溶液反应烧结法制备了单相硼酸镁（Mg2B2O5）纳米棒。由于其令人印象深刻的机械强度和耐热性和耐腐蚀性，硼酸镁纳米棒被广泛应用于增强材料。研究了Mg2B2O5 （MB）纳米棒在700 ~ 1200℃的烧结过程中的表征和物理力学性能。在700 ~ 1200℃之间对合成的MB压实材料的力学性能进行了研究。其高温抗弯强度最大值为42 MPa，室温抗弯强度最大值为53 MPa。在1100℃下，该材料的最大抗压强度为118 MPa，最大硬度为64 HV，是一种很有前途的复合材料增强材料。

Effect of sintering temperatures on physico-mechanical properties of single-phase magnesium borate nanorods

An optimized molar ratio of magnesia (MgO) and boric acid (H₃BO₃) was used to synthesize the nanorod of single-phase magnesium borate (Mg₂B₂O₅) through a solution reaction cum sintering process. Due to their impressive mechanical strength and resistance to heat and corrosion, magnesium borates (MB) nanorods are extensively applicable as reinforcing materials. A meticulous examination was undertaken to assess the characterization and physico-mechanical properties of Mg₂B₂O₅ (MB) nanorods during the sintering process between 700 °C and 1200 °C. Mechanical properties of synthesized MB compacts were investigated between 700 and 1200 °C. The maximum value of high temperature flexural strength (HMOR) and room temperature flexural strength (CMOR) achieved by MB compacts are 42 MPa and 53 MPa respectively. Furthermore, the compacts have a maximum compressive strength of 118 MPa and a maximum hardness of 64 HV at 1100 °C, making it promising reinforcing material for composites.

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
