High Purity Crucibles-Selection Supplier USA

Posted by Manish Singhal on

Crucibles are widely used in thermal and e-beam evaporation, crystal growth, and sintering applications. The two major factors of selecting crucibles are thermal and chemical compatibility.  The temperature range and the degree of corrosion resistant vary based on the crucible materials. The common crucible materials include aluminum oxide, graphite, quartz, boron nitride, tungsten, zirconia etc.

MSE Supplies offers various crucibles and provide custom service. Below are some suggestions and guidelines for finding suitable crucibles

Evaporation deposition

Crucibles can be used in e-beam evaporation and thermal evaporation deposition. The materials to be evaporated are placed in a crucible. It requires high temperature to evaporate the materials. Below are some applications using different crucible materials.

                                                     

Crucible

Alumina

graphite

Recommend Max working temperature

1,600 °C

400 °C (air), 2000 °C (non-oxidizing environment)

Applications

Sb, Au, Co, Cu, Ga, Ge

Sb, B, In, MgO, Cu

                                                       

Crucible

Boron nitride

Quartz

Recommend Max working temperature

900 °C (air), 2100 °C (vacuum), 2000 °C (N2 or Ar)

1200 °C

Applications

MoO3, Au, Sb, Al

ZnSe, AgCl, CoCl, Cs

 

Sintering

Sintering is the process of compacting solid materials by pressure or heat, which is in control of densification and grain growth. Sintering is used in many applications such as metallic powder sintering, ceramic sintering, plastic sintering etc. For example, one of the recent ceramic sintering is used in solid-state electrolyte LLZO densification and grain growth.

                                              

Crucible

MgO

Alumina

Zirconia

Recommend Max working temperature

2,200 °C

1,600 °C

1800 °C (air); 2100 °C (N2 or Vacuum)

 

Applications

LLZO

LLZO

LLZO, Fuel cell electrolyte: Ba(Zr,Ce,Y)O3−δ (BZCY)1

Note

Showed higher Li content and relative density than using alumina crucible2

Al3+ contamination may affect Ga doping

 

 

Crystal growth

Various crystal methods such as Czochralski (Cz) and  Edge-Defined Film-Fed Growth (EFG)  require using crucibles. The Cz crystal growth technology has been used for production of single crystals such as Si and Ge. The Cz method is to melt materials in a crucible and then insert a small seed crystal rod into the melt. The single crystal can be obtained while pulling the seed rod upwards.

(Li et al., 2022)6

                         

MSE Supplies offers various crucibles that are commonly used for crystal growth.

                                             

crucible

Tungsten

Molybdenum

Recommend Max working temperature

1200 °C

Melting point 3407°C

1700 ℃

Applications

Si single crystal

Sapphire crystal3, AIN4

Sapphire crystal5

 

Melting and casting

Melting and casting is the process of making objects by pouring molten materials into a mold. Different metals sometime require different types of crucibles for meting to prevent molten metals to attack crucible or contaminations from crucible. One of the common laboratory applications for melting and casting is XRF sample preparations. The ideal XRF analysis requires perfect flat surface. The fused bead method can provide a good homogeneous representation of the sample for solids. The fused beads are created by mixing samples that is finely powdered with a flux and heating to 900C-1200C in a platinum crucible. The sample is dissolved in the flux, and it is then cast into a mold. 

                                        

Crucible
