Effects of additives in colloidal silica based inorganic-hybrid binder for mineral wool insulation boards

open access: yesJournal of Asian Ceramic Societies, 2020
In the mineral insulation board industry, it has been a challenge to replace the current organic binder to eco-friendly inorganic binder to enhance the fire-resistance, and reduce toxicity.

Seriation Proposed by Kleinschmidt (1982: Table 19) of Allen Phase and Frankston Phase Sites in the Upper Neches River [PDF]

open access: yes, 2007
Kleinschmidt reviewed sherd and vessel collections from a number of Frankston phase (ca. A.D. 1400-1650) and Allen phase (ca. A.D. 1650-1800+) sites in the upper Neches River basin (Anderson, Cherokee, Henderson, and Smith counties) and developed a ...

Tribology of ZrC Coatings and Spherical Tips Acquired with Extraordinarily Stiff, Metal Atomic Force Microscopy Probes

open access: yesAdvanced Engineering Materials, EarlyView.
In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Effect of Al2O3 addition on the non-isothermal crystallization kinetics and long-term stability of BCABS sealing glass for IT-SOFCs

open access: yesJournal of Advanced Ceramics, 2018
Owing to adjustable thermal expansion performance, BaO–CaO–Al2O3–B2O3–SiO2 (BCABS) glass has a promising commercialization prospect for intermediate temperature-solid oxide fuel cells (IT-SOFCs) sealing.

Integration algorithms of elastoplasticity for ceramic powder compaction [PDF]

open access: yes, 2014
Inelastic deformation of ceramic powders (and of a broad class of rock-like and granular materials), can be described with the yield function proposed by Bigoni and Piccolroaz (2004, Yield criteria for quasibrittle and frictional materials. Int.

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Ceramics in Africa

open access: yes, 2008
Pottery making is a very ancient craft in Africa, as some of the oldest pottery remains known in the world were discovered on this continent. Dating from around 10,000 BCE – i.e., one or two millennia after the inception of the Jomon pottery in Japan – they were excavated in the Air Region of Niger (West Africa) (Haour, 2003).

Application of Image Analysis for the Identification of Prehistoric Ceramic Production Technologies in the North Caucasus (Russia, Bronze/Iron Age) [PDF]

open access: yes, 2019
The recent advances in microscopy and scanning techniques enabled the image analysis of archaeological objects in a high resolution. From the direct measurements in images, shapes and related parameters of the structural elements of interest can be ...

Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.
