Quartz crucible is an experimental vessel made of high-purity quartz, which has the advantages of high temperature resistance, corrosion resistance, and good thermal stability. It is commonly used in experimental processes such as high-temperature melting, sintering, and chemical reactions. Its transparency facilitates the observation of internal reactions, making it an indispensable tool in laboratories, and quartz crucibles have high reliability in laboratories.

High temperature resistance

Quartz crucible is made of high-purity quartz material, which has excellent high temperature resistance and can withstand extremely high temperatures. In general, quartz crucibles can withstand temperatures up to 1200 ℃ or higher, and even higher temperatures in short-term applications. Its melting point is about 1670 ℃, much higher than the temperature requirements of conventional high-temperature experiments in the laboratory. In addition, quartz crucibles have a low coefficient of thermal expansion, which can effectively reduce the risk of cracking during rapid temperature changes. Even at high temperatures, they can maintain structural stability without thermal expansion or thermal shock cracking.

Chemical stability

The main component of quartz crucible is silicon dioxide, which has very stable chemical properties and excellent corrosion resistance. It is insoluble, non reactive, and non adsorbent in most common chemical reagents, effectively avoiding contamination and interference of the medium on the sample. Quartz crucibles have good resistance to all acids and bases except for reacting with hydrofluoric acid. Even under high temperature acid-base conditions, quartz crucibles can maintain stability and will not dissolve or corrode, ensuring the accuracy and reliability of experimental results.

Thermal stability

The thermal stability of quartz crucible is good, and it will not undergo brittle fracture or damage at high temperatures, which can maintain the integrity and stability of the structure. This excellent thermal stability enables quartz crucibles to perform well in high-temperature laboratory experiments and operate stably for long periods of time under extreme temperature conditions.

Dimensional stability

Quartz crucibles will not deform or change in size at high temperatures, and can maintain their original shape and structure. This dimensional stability is crucial for the accuracy of the experiment, as it ensures that the volume and shape of the sample are not affected by crucible deformation during the experiment.

Service life

The service life of quartz crucibles is relatively long. Due to its high temperature resistance, corrosion resistance, and thermal shock resistance, quartz crucibles can be reused multiple times under normal use and proper maintenance, thereby saving experimental costs.

Safety

Quartz crucibles do not release any toxic or harmful substances and are harmless to laboratory personnel and the environment. In addition, the chemical inertness of the quartz crucible also prevents it from reacting with the experimental sample, thereby avoiding potential interference with the experimental results.

Widely used

Quartz crucibles are widely used in laboratories, suitable for various chemical reactions, melting tests, and sample heating treatments. It can be used for high-temperature sintering, melting, evaporation and other experiments, as well as for chemical analysis, metallographic experiments, thermogravimetric analysis, etc. In addition, the transparency of quartz crucibles to ultraviolet and infrared radiation makes them very useful in spectroscopic and photochemical applications.

Maintenance

The maintenance of quartz crucibles is relatively simple. After use, it should be ensured that it is dry to avoid moist products from bursting at high temperatures. When storing, it should be placed in a dry and ventilated place, avoiding contact with other hard objects or chemicals, and the storage status should be checked regularly. By proper maintenance and upkeep, the service life of quartz crucibles can be extended and their performance can be maintained.

Limitations and Precautions

Although quartz crucibles have many advantages, there are also some limitations to be aware of when using them. Quartz crucibles are brittle and easily broken, so caution should be taken during use and handling. In addition, quartz crucibles cannot come into contact with hydrofluoric acid and are prone to react with caustic soda and alkali metal carbonates at high temperatures. Therefore, special attention should be paid when using these chemicals.

Quartz crucibles have high reliability in the laboratory, with high temperature resistance, good chemical stability, strong thermal stability, stable size, and long service life, which can meet the needs of various high-temperature experiments and chemical reactions in the laboratory. However, in order to ensure its optimal performance and extend its service life, it is necessary to pay attention to maintenance and upkeep during use, and avoid contact with certain specific chemicals.
