What are Crucibles

Crucibles are essential lab tools that withstand extreme temperatures and harsh chemical conditions. They're containers crafted from high-purity materials like metals and ceramics, ensuring minimal contamination during use. Crucibles are integral to various scientific tasks, including melting, mixing, and analyzing samples under precise temperature and chemical control. With the diversity of materials available, such as Alumina, Zirconia, or Magnesium Oxide, it is critical to select the appropriate type of crucible for your specific application.

Types of Crucibles

What are crucibles made of? Crucibles comprise various materials, including metals, ceramics, and compounds, each suitable for different applications, often based on the crucible melting point. MSE Supplies offers many types of crucibles, including:

• Alumina Crucibles: Widely used due to their high melting points and chemical resistance. Ideal for routine lab research.
• Magnesium Oxide Crucibles: These can withstand ultra-high temperatures and are often preferable to lithium solid-state electrolyte synthesis.
• Zirconia Crucibles: Known for their excellent wear resistance and are suitable crucibles for melting precious metals and super-alloys.
• Boron Nitride Crucibles: Highlighted for their high thermal conductivity and excellent thermal shock resistance.
• Graphite Crucibles: They are the best crucibles for melting metal and induction heating because of their high-temperature resistance.
• Porcelain Crucibles: Economical choice for applications with temperatures below °C.
• Quartz Crucibles: Excellent for material melting and chemical reactions in tube furnaces due to their thermal shock resistance and chemical inertness.

What are the Factors for Selecting a Crucible?

There are several factors one needs to consider when selecting a crucible, this can seem a daunting task because there are several things to consider. These factors can range from needed volume, the shape, and the chemical reactions between the crucible and the chemicals you put in it no name just a couple. Here is a list of some of the most important factors to consider when selecting a crucible. 

• What temperature will the crucible need to withstand?
• What material crucible will be selected?
• Is the material in the crucible going to react with the crucible?
• Is the ramp rate being used going to thermally shock the crucible?
• Is there a thermal gradient across the crucible, if so how will that affect the crucible?
• What volume crucible will I need?
• Will the geometry of the crucible be important?
• Will the crucible fit in the furnace?
• Is the crucible going to be used more than once?

This might seem a daunting list of questions to answer, but if you have ever chosen the wrong crucible for the job and ended up rebuilding your furnace you know the importance of answering these questions. If you need help choosing please continue reading this article. If you still need help our knowledgeable staff at MSE Supplies are here to help.

Alumina (Al2O3) Crucibles

Alumina crucibles (Al2O3) are widely used due to its versatility and its low cost. It is the most commonly used crucible for lab research use. The material has a high melting point is and relatively chemically inert. MSE Supplies offers a wide variety of shapes and sizes of Alumina crucibles.  If you need a size or shape not listed on our website, please us at . 

Magnesium Oxide (MgO) Crucibles

Magnesium Oxide (MgO) crucibles are good for ultra high temperatures and have a better chemical resistivity than that of alumina. MgO crucibles are usually inert to metals, slags, and superconducting compounds. When MgO crucibles are used in lithium solid state electrolyte synthesis or sintering, MgO has its own unique advantage of not reacting with lithium unlike Al2O3 crucibles, therefore it maintains the lithium vapor pressure better without causing access lithium loss in the solid state electrolyte.
