The material with dimensional and thermal stability manifested their importance in widespread applications from kitchen to cosmos. 1,2 Lithium aluminosilicate (LAS) glassceramic is one of such material attracted research as well as industrial community due to their properties namely low coefficient of thermal expansion (CTE), thermal shock resistance, chemical durability, and mechanical strength. [2][3][4] Attracted by their thermal properties, LAS glass-ceramics are studied for dielectric properties. 5,6 The process of making low expansion glass-ceramic (LEGC) relies on precipitating high-quartz type LAS based negative thermal expansion (NTE) crystals uniformly throughout the glass matrix. 7 These stuffed derivatives of quartz structure proposed by Buerger 8 and Li et al. 9 are comparable with magnesium aluminosilicate based -cordierite system. 10 Mg 2+ ions occupy octahedral coordination sites, and Zn 2+ ion occupies tetrahedral sites in high-quartz type crystals. Zn 2+ substitution in the LAS crystals system can result in very high NTE behavior whereas Mg substitution results in low positive thermal expansion (PTE). Mg substitution up to 20% allows the precipitation of high-quartz type s.s. 11 The addition of MgO with CaO in LAS glass system was reported to reduce the crystallization temperature. 12 Alekseeva et al. 13 reported that the addition of PbO, MgO, BaO in LAS glass improves the precipitation of quartz solid solution and ZnO, Na 2 O, and K 2 O addition accelerates the crystallization process. BaO addition in LAS glass reported yielding better dielectric properties. 14 In LAS GC precipitating high-quartz

“…Pressure-assisted reactive sintering was used to produce many (also non-metal) composites such as ZrB2-SiC-ZrC [20], B4C/Li2O-Al2O3-SiO2 [21], Al-Si [22], ZrB2-SiC-ZrO2 [23], TiC/Ti3SiC2 [24] or reinforced Al matrix composites [3] [25]. Depending on material and processing conditions, porosity varied between 2.4% [21] and 26% [24]. Al-NiO composite had a porosity between 5-8.7% [25] and no porosity measurement was conducted for Al-Mg composite in [3].…”

Lightweight materials like Al-Mg composite are attractive especially for aerospace or automotive industry. Current paper investigates mechanical behaviour of hot-pressed, reactive sintered Al-Mg composite with initial Mg volume content of 60% using finite element simulation. Conducted numerical simulations study effect of the porosity on mechanical behaviour. Overall porosity (in percent) is decisive factor for mechanical behaviour of investigated Al-Mg composite rather than number or size of pores.

Electrolysis of seawater can be a promising technology, but chloride ions in seawater can lead to adverse side reactions and the corrosion of electrodes. A new transition metal boride‐based self‐supported electrocatalyst was prepared for efficient seawater electrolysis by directly soaking nickel foam (NF) in a mixture of phenolic resin (PR) and boron carbide (B4C), followed by an 800 °C annealing. During PR carbonization process, the reaction of B4C and NF generated nickel boride (NixB) with high catalytic activity, while PR‐derived carbon coating was doped with boron atoms from B4C (B−CPR). The B−CPR coating fixed NixB/B4C particles in the frames and holes to improve the space utilization of NF. Meanwhile, the B−CPR coating effectively protected the catalyst from the corrosion by seawater and facilitates the transport of electrons. The optimal NixB/B4C/B−CPR/NF required 1.50 and 1.58 V to deliver 100 and 500 mA cm−2, respectively, in alkaline natural seawater for the oxygen evolution reaction.
