Products Description
Circular graphite boat is a container made of graphite material, mainly used in semiconductor, photovoltaic and other industries. In these industries, graphite boats are usually used to carry materials such as silicon wafers for coating and other processing. Because graphite has the characteristics of high temperature resistance and good chemical stability, the graphite boat can work stably in harsh environments such as high temperature and chemical corrosion, ensuring the smooth progress of the production process.
Product features
1.High temperature resistance
Graphite has an extremely high melting point, exceeding 3000°C. This allows the graphite boat to maintain structural stability in high-temperature environments and will not melt or deform easily. In high-temperature processes such as physical vapor deposition (PVD) in the photovoltaic industry, graphite boats can withstand temperatures above 1,000°C to ensure the smooth progress of the production process.
2.High thermal conductivity
Graphite has good thermal conductivity properties. The graphite boat can quickly and evenly distribute heat on its surface, ensuring that materials such as silicon wafers placed on it are heated evenly. This uniform heating helps improve the stability of the production process and product quality.
3.Good chemical stability
Graphite hardly reacts chemically with common acid, alkali and salt solutions at room temperature. In high-temperature environments, graphite boats also have good tolerance to various reactive gases in the coating process and are not easily corroded. This enables the graphite boat to be used stably in various chemical vapor deposition (CVD) scenarios over the long term.
4.Antioxidant
Within a certain temperature range, graphite boats have good anti-oxidation properties. Although graphite will react with oxygen at extremely high temperatures, at the temperature conditions found in most industrial applications, graphite boats can be effectively prevented from oxidation through surface treatment or use under inert gas protection.
5.Excellent electrical conductivity
Graphite itself is a good conductor of electricity. In some plasma-enhanced vapor deposition processes, graphite boats can be used as part of the electrode to assist in achieving uniform distribution and conduction of plasma, helping to form a uniform, high-quality film on the surface of the material to be processed.
6.self-lubricating
Graphite has a natural self-lubricating effect, which makes the graphite boat in and out of some automated production equipment smoother, reduces mechanical friction loss, and extends the service life of the equipment and the graphite boat itself.

FAQ
What is the high temperature resistance of graphite products?
Graphite has excellent high temperature resistance. Ordinary graphite products can work stably at high temperatures of around 2000°C, while some special high-purity graphite products can even withstand higher temperatures.
What is the chemical stability of graphite?
Graphite has good stability to most chemicals. At normal temperature, it does not react with acids, alkalis, salts, etc. However, at high temperatures, oxidation reactions may occur when in contact with strong oxidants.
Does graphite have good thermal conductivity?
Graphite has very good thermal conductivity and is a good thermal conductive material. It has a higher thermal conductivity than many metals, allowing it to transfer heat quickly and evenly.
How to judge the quality of graphite products?
The quality of graphite products can be judged from the following aspects: first, look at the appearance, the surface should be smooth, without cracks, and without impurities; secondly, check the density, graphite products with high density usually have better quality; you can also test their electrical conductivity, thermal conductivity, etc. indicators to assess quality.
