Combustion synthesis of ultra‐high temperature ceramics: Review

International Journal of Applied Ceramic Technology, Volume 22, Issue 6, November/December 2025.
Abstract Novel and future‐oriented aerospace, energy, transportation, and other industrial technologies require materials capable of operating at temperatures above 2000°C. Ultra‐high temperature ceramic materials (UHTCs), based on carbides, borides, carbonitrides, and nitrides of transition metals—many with melting points exceeding 3000°C—possess the ...

In-situ processing of NiAl–alumina composites by thermite reaction

Materials Science and Engineering: A, 2000
Abstract NiAl–Alumina composites have been fabricated by reactive sintering of ball-milled and compacted powder mixtures containing NiO and Al. Dense NiAl–Al 2 O 3 composite with an interpenetrating Al 2 O 3 network was fabricated after 2 h of vacuum hot pressing at 1200°C and 50 MPa.

Thermite assisted synthesis of ZrB2 and ZrB2–SiC through B4C reduction of ZrO2 and ZrSiO4 in air

Journal of Advanced Ceramics, 2017
ZrB2 and ZrB2–SiC powders have been produced by reducing ZrO2 and ZrSiO4 with B4C without using any furnace. Magnesium was added to the mixtures of (ZrO2+B4C) and (ZrSiO4+B4C).

A survey of explosive traces in public places

Journal of Forensic Sciences, Volume 70, Issue 4, Page 1450-1459, July 2025.
Abstract Interpretation and evaluation of trace explosives evidence requires practitioner understanding of factors including transfer, persistence, and environmental prevalence. This study builds on previous work and studies the contemporary prevalence of organic high explosives and inorganic ions of explosives significance in public places.
