The product is Factory Supply Glassy Carbon with CAS 68647 - 86 - 9. Glassy carbon, also known as vitreous carbon, is a non-graphitizing carbon which combines glassy and ceramic properties with those of carbon. It has a smooth, impermeable surface and excellent chemical resistance. The glassy carbon from our factory is supplied at the best price in the market, ensuring high - quality products with cost - effective solutions.
Some of its key parameters are as follows: High purity, usually above 99%. It has a relatively low density, around 1.4 - 1.5 g/cm³. Its thermal expansion coefficient is very low, which makes it suitable for applications in high - temperature environments. It also has good electrical conductivity, comparable to some metals in certain conditions.
1. **Electrochemical Applications**: Glassy carbon is widely used as an electrode material in electrochemistry. Its high electrical conductivity, chemical inertness, and wide potential window make it ideal for various electrochemical experiments and industrial processes. For example, it can be used in cyclic voltammetry to study the redox behavior of different substances.
2. **Analytical Chemistry**: In analytical instruments, glassy carbon is often used as a sample holder or a component in atomic absorption spectroscopy and other analytical techniques. Its smooth surface and low background signal ensure accurate and reliable analysis results.
3. **High - temperature Applications**: Due to its low thermal expansion coefficient and high thermal stability, glassy carbon can be used in high - temperature furnaces, crucibles, and other high - temperature equipment components. It can withstand high temperatures without significant deformation or chemical reaction.
1. **Electrode Preparation**: When using glassy carbon as an electrode, first, it needs to be polished carefully to obtain a smooth surface. A series of polishing steps using different grits of polishing papers and polishing compounds are usually required. After polishing, the electrode should be rinsed thoroughly with deionized water and dried. Then, it can be modified with appropriate substances if needed for specific electrochemical applications.
2. **Sample Holder Installation**: In analytical instruments, the glassy carbon sample holder should be installed according to the instrument's instructions. Make sure it is properly positioned and fixed to ensure accurate sample analysis.
3. **High - temperature Use**: When using glassy carbon in high - temperature equipment, it should be installed in a proper position and the equipment should be heated and cooled gradually to avoid thermal shock. The maximum temperature and heating rate should be within the allowable range of the glassy carbon material.
1. **Electrochemical Sensor Development**: A research group used our glassy carbon to develop an electrochemical sensor for detecting heavy metal ions in water. By modifying the glassy carbon electrode with a specific nanomaterial, they achieved high - sensitivity and selective detection of heavy metal ions. The sensor showed excellent stability and reproducibility, which is very useful for environmental monitoring.
2. **High - temperature Furnace Linings**: A manufacturing company used our glassy carbon as the lining material for a high - temperature furnace. The glassy carbon lining withstood the high - temperature environment for a long time without significant damage, which improved the service life and performance of the furnace.
3. **Analytical Instrument Upgrade**: An analytical laboratory replaced the original sample holder with our glassy carbon sample holder in an atomic absorption spectrometer. The new glassy carbon sample holder reduced the background signal and improved the detection accuracy of trace elements in samples.
