Design FeaturesZirconia ceramic crucibles with lids, also known as corrosion-resistant and high-temperature ceramic grinding jars, feature several carefully 

designed characteristics to withstand harsh industrial and laboratory environments:

Structure and Design

The crucible design includes a smooth outer shell and a tightly fitting lid. This design effectively prevents sample contamination and loss 

of volatile substances during heating, while also increasing thermal efficiency and helping to maintain a constant internal temperature.

Thermal Efficiency and Safety

The lid not only enhances thermal efficiency and makes the temperature more uniform, but also protects the operator from direct exposure 

to high temperatures, ensuring the safety of experiments and production.

Material Advantages

Zirconium oxide ceramic has a coefficient of thermal expansion of 9.6 × 10⁻⁶ °C and high thermal shock resistance up to 250 °C. These 

properties allow the crucible to withstand drastic temperature changes, making it ideal for applications requiring frequent heating and 

cooling.

Chemical Stability and Durability

Zirconium oxide ceramic exhibits excellent chemical stability and 0% water absorption, ensuring corrosion resistance and long-term 

durability when handling strong acids, strong alkalis, or other corrosive substances.

Application areasLidned zirconia ceramic crucibles excel in several demanding applications, particularly in environments requiring high temperatures, 

high purity, and chemical stability:

High-Temperature Chemical Reactions

Due to their high-temperature resistance and chemical stability, these crucibles are ideal for a wide range of high-temperature chemical 

reactions, capable of withstanding continuous thermal cycling without compromising performance.

Metal and Ore Smelting

The crucibles' heat resistance and resistance to chemical corrosion make them ideal for smelting metals and ores, especially when refining 

high-purity metals.

Scientific Research and Material Analysis

In scientific research and material analysis, precise temperature control and prevention of sample contamination are crucial, and lidded 

zirconia ceramic crucibles provide the necessary conditions.

With their excellent design and superior material properties, lidded zirconia ceramic crucibles offer reliable solutions for demanding 

experimental and industrial environments. Their structural design optimizes thermal efficiency and chemical stability, ensuring efficient 

and safe operation under extreme conditions. These crucibles are indispensable tools in high-temperature, high-purity experiments and 

production activities, showcasing the high performance and adaptability of zirconia ceramic materials.
