The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

{{Periodic table (melting point)|state=expanded}} or {{Periodic table (melting point)|state=collapsed}}This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
T m = melting or freezing temperature of the liquid (in kelvins), T 0 = initial temperature of the mold (in kelvins), ΔT s = T pour − T m = superheat (in kelvins), L = latent heat of fusion (in [J·kg −1]), k = thermal conductivity of the mold (in [W·m −1 ·K −1)]), ρ = density of the mold (in [kg·m −3]), c = specific heat of the ...
For example, the melting and freezing points of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). [2] However, certain substances possess differing solid-liquid transition temperatures. For example, agar melts at 85 °C (185 °F; 358 K) and solidifies from 31 °C (88 °F; 304 K); such direction dependence is known as hysteresis.
Mold grows best in warm temperatures, 25 to 30 °C (77 to 86 °F), although growth may occur between 0 and 35 °C (32 and 95 °F). [ citation needed ] Removing one of the three requirements for mold reduces (or eliminates) new mold growth: moisture; food for the mold spores (for example, dust or dander ); and warmth since mold generally does ...
Common scales of temperature measured in degrees: Celsius (°C) Fahrenheit (°F) Rankine (°R or °Ra), which uses the Fahrenheit scale, adjusted so that 0 degrees Rankine is equal to absolute zero. Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The ...
The oven temperature should be less than the melting temperature of the bullet alloy. This temperature will vary with the concentrations of alloying elements; but is often in the range of 450 to 500 degrees Fahrenheit (232 to 260 degrees Celsius).
