On the Conservatisms of Nepheline Predictors for Canister Centerline Cooled (CCC) High‐Level Waste (HLW) Glasses

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Multiple models and feature sets have been generated, which attempt to predict the crystallization of nepheline (NaAlSiO4) in high‐level radioactive waste (HLW) glasses under canister centerline cooling (CCC) conditions. Earlier models were found to be overly conservative, while newer models had a not insignificant rate of false positives and ...

Influence of Processing Variables on the Hydrothermal Synthesis of Zeolite–Geopolymer Aggregates from Kaolin

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT This study addresses the influence of key processing variables on the hydrothermal alkaline treatment of low‐temperature fired kaolin‐aggregates for the development of zeopolymers (zeolite–geopolymer composites). Parameters such as hydrothermal treatment temperature (90 and 150°C), reactor volume (250 and 500 mL), liquid‐to‐solid (L/S) ratio ...

Low‐Temperature Hydrothermal Synthesis of PbUO4

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
A low‐temperature hydrothermal route for synthesizing phase‑pure orthorhombic PbUO4 is demonstrated using metaschoepite and lead nitrate at 150°C–240°C. Systematic variation of pH, temperature, and reaction duration reveals that PbUO4 formation is strongly controlled by solution chemistry, with hydrated Pb‐U phases forming at lower pH and direct ...

Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

open access: yesAdvanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Characterization of Macro/Microstructure and Corrosion Resistance of Austenitic Gas Tungsten Arc Welding Cladding

open access: yesAdvanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.
