Crucibles

Introduction

Crucibles serve as material container for all MBE effusion cells and industrial sources. Materials used in MBE applications have different requirements concerning evaporation temperatures and chemistry. Therefore different suitable crucible materials can be applied. The shape of the crucibles influences the beam shape. The beam shape can additionally be adjusted using Beam shaping inserts (BSI) for cylindrical crucibles from Dr. Eberl MBE Komponenten in order to save material and improve beam uniformity.

Specifications

Crucibles are characterized by their loading volume. Crucibles from Dr. Eberl MBE-Komponenten are designed to match the evaporation temperature and the effusion cell geometry. The crucibles described in the following table are crucibles used in our MBE sources. For each crucible the respective part number, product code is indicated. The crucible product code specifies material, nominal capacity (in cm³), lip diameter (in mm) and features. The nominal capacity is consistent with the capacity of the corresponding sources. The maximum dimensions of loading material chunks can be estimated based on the specified volume and the crucible length.

$d=\sqrt{\frac{12\cdot \mathrm{Volume}}{\pi \cdot \mathrm{LC}}}$

In case of bottle neck crucible the maximum size of material chunks is limited by the bottle neck diameter. Drawings are not to scale and shall not be used for manufacture. No responsibility is taken for the correctness of the values.

Product code: CRU 10–22-PBN-D
Product description: Crucible with 10 cm³ nominal charge, lip diameter 22mm, made from PBN, double wall

Available crucible materials

	Material	Max. temperature [°C]
PBN	pyrolytic boron nitride	1500
PG	pyrolytic graphite	2000
Al2O3	aluminium oxide	1600
Quartz	silicon dioxide	800
BeO	beryllium oxide	1750
Ti	titanium	800
W	tungsten	2000
Ta	tantalum	2000
Ir	iridium	2000
ST	stainless steel	300

*The maximum temperature permitted during outgassing/operation can be significantly lower as listed above because it depends on several interacting factors, e.g., thermocouple type, filament material, crucible material, evaporant and application. The restriction with the lowest value leads to the final maximum admissible temperature. Please always observe the maximum temperature values specified in the respective operating instructions.

Crucible list

The following lists shows all available crucibles. The tables are sorted by lip diameter and volume.
