Discussion History

Furnaces, Gas and Vacuum

Assembly

A box furnace fires pellets and powders in air, and a tube furnace with regulators, a flow meter and a rotary vane pump fires them in flowing oxygen or argon after pump-down. An arc melter and quartz ampoules sealed with a torch make intermetallics, which an oxide-only program can skip. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

#PartQtyWhat it does
1 Muffle Furnace 10 parts 1× Fires pressed pellets and loose powder in air for calcination and sintering. Core
2 Tube Furnace 1× Fires samples in flowing oxygen or argon, or under rough vacuum, inside a sealed work tube. Core
3 Furnace Work Tube 2× Holds the sample and the gas atmosphere inside the tube furnace and is replaced when it cracks or devitrifies. Core
4 Vacuum Sealing Flange Set 1× Seals both ends of the work tube and carries the gas inlet, gas outlet, vacuum port and pressure gauge. Core, set
5 Alumina Crucibles and Boats 20× Holds powder or pellets during firing, with boats for the tube furnace and crucibles for the box furnace. Core
6 Crucible Tongs 2× Moves hot crucibles and boats in and out of the furnace. Core
7 Thermocouple Probe and Reader 1× Measures the temperature along the furnace hot zone to check the controller reading and find the uniform region. Useful, set
8 Two-Stage Gas Regulator 4× Reduces cylinder pressure to a steady low delivery pressure for the furnace gas line or the torch. Core
9 Gas Flow Meter 2× Sets and displays the gas flow through the work tube during a run. Core
10 Gas Tubing and Compression Fittings 1× Carries gas from the regulators through the flow meter to the furnace flange and on to the bubbler. Core, set
11 Oil Bubbler 1× Vents the furnace exhaust through oil so room air cannot diffuse back into the tube and the gas flow is visible. Useful
12 Rotary Vane Vacuum Pump 1× Evacuates the work tube before backfilling with gas and pumps down quartz ampoules before sealing. Core
13 Vacuum Gauge 1× Reads the pressure in the tube or ampoule line to confirm pump-down and reveal leaks. Useful
14 Vacuum Valve and KF Fittings 1× Connects the pump to the furnace flange or ampoule and isolates the pump so the tube can be backfilled with gas. Core, set
15 Fused Quartz Tubing 10× Forms the sealed ampoules that hold air-sensitive or volatile reactions under vacuum or argon. Useful
16 Glassworking Torch 1× Melts and collapses fused quartz tubing to seal ampoules while they are held under vacuum. Useful
17 Fuel Gas Cylinder 1× Supplies the hydrogen or propane that the glassworking torch burns with oxygen to seal quartz ampoules. Useful, cylinder
18 Arc Melter 1× Melts metal pieces together under argon on a water-cooled copper hearth to make intermetallic buttons. Useful
