Ceramic crucibles, graphite crucibles and metal crucibles differ in terms of their properties and suitable applications:
Generally, ceramic crucibles and metal crucibles have lower thermal conductivity compared to graphite crucibles. And metal crucibles typically exhibit greater thermal conductivity than ceramics. This means that ceramic crucibles may take longer to heat up and cool down.
Typically chemically inert and corrosion-resistant, ceramic crucibles are ideal for applications where potential reactions with the crucible material are a concern. While graphite is generally resistant to most chemicals, it can react with specific gases or substances, particularly at high temperatures. And depending on the metal or alloy used, metal crucibles may be susceptible to corrosion or chemical reactions with certain substances. Some metals, like stainless steel, are more corrosion-resistant than others.
Renowned for withstanding temperatures over °C, ceramic crucibles are ideal for high-heat processes such as metal casting and glass melting. However, the specific graphite type and material impurities can affect their performance. While the temperature resistance of metal crucibles depends on the specific metal or alloy used. and many metals can withstand high temperatures, they may have limitations compared to graphite in certain extreme conditions. For applications requiring extremely high temperatures, ceramic crucibles might be slightly superior.
Graphite crucibles are durable and resistant to thermal shock. However, they can be brittle and may be more susceptible to physical damage compared to metals. Also, ceramic crucibles are more prone to cracking or chipping if subjected to mechanical stress. While metals are generally more ductile and malleable, making metal crucibles more resistant to mechanical stress and physical damage.
Ceramic Crucibles are commonly used in applications requiring chemical corrosion resistance and high-temperature stability, like in the analysis of minerals, metals, and ceramics. While graphite crucibles are popular in metallurgical applications, jewelry crafting, and procedures involving high temperatures, such as metal and alloy melting. And metal crucibles are typically used in applications depending on the specific metal or alloy and requiring durability. For example, stainless steel crucibles are used in laboratory and industrial settings, while platinum crucibles may be used in high-precision applications.

High pressure crucible small Stainless steel, gold plated
Feature:
1. The gold-plated steel crucible 25 uL (fast) and 40 uL have proven highly effective in the field of safety investigations. However, they can only be used for one measurement each. The maximum pressure is 22 MPa.The crucible lid is pressed into the crucible with the aid of a toggle press with a pressure of about a ton so that the rupture disk (Gold, Au 700/531) hermetically seals the crucible.
To ensure heat transfer efficiency between sample and sensor, please select a quality sample pan/crucible with a suitable temperature range
to conduct an experiment, so as to get the most accurat effect.
