99.3% Alumina Ceramic Arc Crucible 10 mL ATOMFAIR®

What is the maximum operating temperature of the 99.3% alumina ceramic arc crucible?

The product description specifies a 99.3% alumina ceramic material but does not state a maximum operating temperature. For high-temperature applications, verify the thermal rating with the manufacturer, as 99.3% alumina typically withstands up to 1750°C in air, but this is not confirmed by the source.

Does the 10 mL arc crucible fit standard laboratory holders designed for 29 mm top outer diameter?

Yes, the crucible has a top outer diameter of 1.142 in (29 mm) and a lower outer diameter of 0.709 in (18 mm), with a height of 1.339 in (34 mm). These dimensions allow direct compatibility checks against holders or furnace ports requiring a 29 mm top OD and 18 mm base OD, but the source does not list specific holder models.

What is the wall thickness of the crucible and how does it affect thermal shock resistance?

The wall thickness is 0.079 in (2 mm). A 2 mm wall provides moderate thermal mass; thinner walls reduce thermal gradients and improve thermal shock resistance in alumina ceramics, but the source does not provide thermal shock data or recommended heating/cooling rates for this specific crucible.
