Microanalysis of Hafnian Zircon [PDF]
Microscopy and Microanalysis, 2005 As revealed by FE-SEM and electron probe microanalysis, we report that hafnian zircon (Zr,Hf)SiO_4 with Hf/Zr atomic ratio up to 1.0 is present in the famous Stewart pegmatite, Pala District, San Diego County, California. The Stewart mine, as part of the gem-bearing and rare element- bearing granitic pegmatites in Southern California, has been mined

Significant Zr isotope variations in single zircon grains recording magma evolution history
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Zircon, a common accessory mineral in crustal rocks, records plentiful and critical information on the Earth’s history. The isotopes of its major component, Zr, could be another powerful but unexplored tracer.

Application of Ti-in-zircon thermometry to granite studies: problems and possible solutions
Contributions to Mineralogy and Petrology, 2019 The application of the Ti-in-zircon thermometer to granitic rock requires consideration of $$a_{{{\text{TiO}}_{2} }}$$aTiO2 and $$a_{{{\text{SiO}}_{2} }}$$aSiO2 during zircon crystallization.

Advanced Engineering Materials, EarlyView.Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

Zircon saturation in terrestrial basaltic melts and its geological implications
Solid Earth Sciences, 2019 Zircon is a widely used accessary mineral, and zircon saturation in silicate melts has many applications in geology. Based on the original model proposed by Watson and Harrison (Earth Planet. Sci. Lett. 64:295–304, 1983), the quantification of the zircon

Single‐Crystal Castability of CM186LC Nickel‐Based Superalloy
Advanced Engineering Materials, EarlyView.The optimal conditions to obtain single‐crystal (SX) castings of the directional solidification nickel‐based superalloy CM186LC, are investigated. Cylindrical samples are cast via a proprietary SX Bridgman process. The effect of solidification rates (V) ranging from 1 to 10 mm⋅min−1 on the microstructure is explored.
