04/07/2014 · Zircons in ~ Ma felsic lava show Tiinzircon evidence for limited new zircon growth in relatively hot magmas (Ti = ~19 ppm; 850 °C), though nowhere near as warm as those of the prePST trachytes and Moss (Ti = ~30 ppm; 900 °C); this may reflect limited periodic magmatic recharge throughout the volcanic center's postPST history.
11/05/2017 · When it gets HOT, like really F'n HOT!!! 1700F'ish.. It gets harder than hell, I vaguely remember reading well over 100+ on the Cscale, and it gets slicker than snot. I'll run this on dry on mild steels, 4140's, 1018 type stuff. Wet in Ti, and stainless.. Depending on how you are running you can get away with dry and faster on some stainless ...

17/02/2021 · Thermal Conductivity. Thermal conductivity is the measure of a substance's ability to transfer heat through a material by conduction. We are dealing with conduction today. The reason applying intense heat to a small, localized portion of a zirconium crown is that zirconium is an extremely poor conductor of heat.
