Alumina Crucible
Aluminum oxide (Al2O3) is a very durable material that can withstand high temperatures of one to two thousand degrees. It also has many advantages, such as good thermal stability and thermal conductivity, strength and toughness, etc. Due to their high resistance to chemical attack and high temperature resistance, alumina drying crucibles and other forms of alumina crucibles are often used in high temperature reactions such as aluminum, titanium and magnesium.
The above are several common crucible materials, each with its specific uses and advantages. The reason why the crucible can withstand molten iron of more than 1,000 degrees is due to the combined influence of various factors such as the material, shape and use of the crucible.
For example, a high-quality graphite crucible can withstand reactions under high temperatures and strong acid/alkaline conditions, which is related to its unique structure. Graphite crucibles are manufactured using high-temperature ovens and ceramic coating processes. Graphite films and glass phases are formed on the inner and outer surfaces respectively, and serial treatments are completed in a suspended state. However, it should be noted that even high-quality graphite crucibles will experience a continuous heat transfer process, so they often need to be maintained and maintained during experiments.
In addition, some new crucible materials have begun to be widely used. For example, new materials such as molybdenum, molybdenum defects and nanoscale ceramics have high melting points and corrosion resistance, and are increasingly attracting the attention and favor of scientists and businesses.
In general, the crucible is a vital tool that plays an irreplaceable role in the research field of metals and materials science. Selecting the most suitable crucible material for experimental purposes is a complex process that requires consideration of various factors such as the material's physical and chemical properties, temperature range, acid and alkali resistance, and durability. However, no matter which type of crucible is used, its stable structure and excellent high temperature resistance will provide reliable guarantee for experiments, making it one of the powerful tools for exploration in this field.
