Product Description

Product Description

TANTALUM CRUCIBLE

Tantalum crucible has a series of excellent properties such as high melting point, low vapor pressure, good cold processing performance, high chemical stability, strong resistance to liquid metal corrosion, and high dielectric constant of surface oxide film. It is widely used in container crucibles for sintering sapphire, container crucibles for arc furnaces, and various containers that require complex processing and use conditions. Tantalum crucibles can be used to melt sapphire.

Tantalum has the characteristics of a high melting point and good chemical stability. During the smelting process of sapphire (the main component is alumina), it can withstand a high-temperature environment, and the possibility of contamination of sapphire raw materials is low, which can ensure a relatively pure environment for the growth process of sapphire. However, it is also necessary to strictly control the process conditions during use to ensure that the performance of the crucible is fully utilized in order to successfully melt high-quality sapphire.

HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

The melting point of tantalum is as high as 2996ºC, ranking fifth in the single substance. This makes the tantalum crucible stable in a high-temperature environment, can withstand the temperature requirements of most materials melting, sintering,g and other high-temperature treatment processes, and is suitable for rare earth smelting, high-temperature sintering, and other work scenarios.

EXCELLENT CHEMICAL STABILITY:

Whether in cold or hot conditions, tantalum does not react to hydrochloric acid, concentrated nitric acid, and "aqua regia", and only in hydrofluoric acid, hot concentrated sulfuric acid, phosphoric acid at high temperature, and other cases will be corroded. This characteristic makes it not easy to erode when dealing with various chemical substances and can be used for the treatment of corrosive substances in a variety of chemical experiments and industrial production, such as excellent performance in equipment for making various inorganic acids.

GOOD DEFORMATION RESISTANCE:

Tantalum has a very small thermal expansion coefficient, with an expansion of only 6.6ppm per degree Celsius, and its toughness is very strong, which makes the tantalum crucible less likely to deform when the temperature changes, and can maintain good dimensional stability, which helps to ensure the accuracy and repeatability of the experiment or production process.

GOOD PROCESSING PERFORMANCE:

Tantalum has moderate hardness and ductility and can be drawn into filaments or made into thin foils, which makes tantalum crucibles easy to process into various shapes and sizes to meet the needs of different application scenarios.

REUSABILITY:

If used and maintained properly, tantalum crucibles can be reused many times to reduce the cost of use.
