Recycling of inorganic waste in monolithic and cellular glass-based materials for structural and functional applications [PDF]
, 2016 The stabilization of inorganic waste of various nature and origin, in glasses, has been a key strategy for environmental protection for the last decades. When properly formulated, glasses may retain many inorganic contaminants permanently, but it must be

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Effects of CeO2 on Bi2O3-rich Lead-free Sealing Glass Ceramics [PDF]
, 2012 传统上，国内外电子与电器设备上的电热管常用的封接材料是含Pb微晶玻璃；但是，由于含Pb玻璃有毒，美日欧及我国等先后采取了相关措施，对封接材料的含Pb量作了严格法律的限制。因此，研制无Pb封接微晶玻璃具有十分重要的意义。本研究作为制备结构材料，对于Bi2O3原料的纯度要求不高，可提取自某些稀土尾矿，CeO2如能应用于封接用无Pb封接微晶玻璃，则对尾矿处理、稀土综合利用和轻稀土大量堆积等问题的解决有积极的作用，且加入少量CeO2可以有效提高封接玻璃与添加铈的合金的结合能力。 本研究在全面深入的调研的基础上 ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...
