, 2011 采用溶胶-凝胶法利用水解反应制备了纳米Ag粒子与SiO2复合的nano-Ag∶SiO2薄膜,通过对Ag纳米粒子局域表面等离子体共振（SPR）吸收光谱的观测,探讨了薄膜的热稳定性。利用TG-DSC、XRD、TEM、SEM和EDS等对nano-Ag∶SiO2的物性进行了研究。结果表明：nano-Ag∶SiO2薄膜在不同温度（200～900℃）下热处理,随着热处理温度的升高,薄膜中Ag纳米粒子的SPR特征吸收峰从无到有并逐渐增强,500℃、600℃峰值强度最强,然后逐渐减弱至消失;薄膜500 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Refractory complex‐concentrated alloys (RCCAs) show exceptional promise for extreme‐environment applications, yet intermediate‐temperature instability (0.4–0.6 Tm) and plasticity degradation severely constrain their development. This work provides an effective strategy to transform the inherent intermediate‐temperature instability into a ...

Dianci bileiqi, 2005 采取提高热处理温度、延长保温时间等措施,改善直径大且厚的电阻片老化性能,取得了较好的效果。试验证明,热处理工艺可使电阻片的压比明显降低;在0.75U1mA下的阻性电流除少数外均有不同程度的增大,总的规律是尺寸大的比小的增大得多;热处理可明显提高电阻片的方波通流能力,并改善其稳定性。欲通过热处理使电阻片的性能获得最佳,必须根据电阻片的尺寸、烧成制度等调试热处理炉的温度制度及装片密度,选定较合理的工艺。采用再次热处理的方法使已抽查试验的电阻片性能得到恢复。通过X衍射试验 ...

Gongye shui chuli, 2017 针对剩余污泥中有机能源利用率低的问题，研究了水热预处理对剩余污泥有机物释放及污泥厌氧消化过程中累积产气量的影响。结果表明：水热处理是一种有效的污泥预处理方法，当水热温度为200 ℃、水热时间为1 h时，污泥减量度达76.56%，污泥SCOD为原泥的34倍，大大减少了污泥固相有机物含量。经水热处理后，污泥厌氧消化最大产气量为2 950 mL，较原泥提高了69%；厌氧消化后，水热预处理污泥SCOD减少量为原泥的30倍。

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

四川大学学报. 自然科学版, 2015 本文利用微波热处理法,分别在大气和氮气气氛两种情况下快速再生了已经充分吸附SO2的颗粒状活性炭.微波热处理过程中,应用红外热成像技术,采集了样品的一系列热图像,直观显示了温度分布,表明热处理的最高温度仅为300℃.将再生产物用于模拟烟气脱硫实验,结果表明大气气氛下,微波再生活性炭的脱硫性能还不及原炭的一半;换以氮气气氛隔绝空气后,其脱硫性能提升到原炭的97%.隔绝空气条件下的微波热处理再生法比传统热再生方法,降低了处理温度、极大缩短了再生时间,体现了高效、低能耗两大优势.
