Black Phosphorus: A Pioneer of Future Materials
In recent years, with the rapid advancement of technology, the research and application of new materials have become focal points across various fields. Among them, black phosphorus, as a novel two-dimensional material, has attracted widespread attention due to its unique physical and chemical properties. Black phosphorus not only shows immense potential in the fields of electronics and optoelectronics but also presents broad application prospects in energy, environmental, and other sectors.
Figure 1: Crystal Structure of Black Phosphorus
Black phosphorus is an allotrope composed of phosphorus atoms, featuring a layered structure that can exist in both single-layer and multi-layer states. Its unique bandgap properties make it highly valuable for applications in the semiconductor field. Compared to graphene, black phosphorus exhibits superior performance in areas such as photoelectric conversion, sensors, and batteries. As a result, the research and development of high-quality black phosphorus materials have become a shared goal for both the scientific and industrial communities. While research on black phosphorus began in the last century, significant breakthroughs have only occurred in the past decade.
Early preparation methods were diverse, but they faced technical challenges such as low yield, insufficient purity, and high costs. For example, the traditional high-pressure method, although capable of producing high-purity black phosphorus, is limited by complex operations and expensive equipment, which hinder large-scale production. The high-pressure method typically requires extremely high pressure (around 1.2 GPa) and high temperatures (approximately 1000°C), which not only increase production costs but also demand stringent requirements on equipment and operators. Although the high-pressure method can produce high-purity black phosphorus, its low yield and high cost make it difficult to meet the demands of industrial-scale production.
However, the advent of the Chemical Vapor Transport (CVT) method has changed this situation. The CVT method not only enables the preparation of high-quality black phosphorus under lower temperature and ambient pressure conditions but also significantly increases yield and reduces costs. This technological breakthrough has paved the way for the commercialization of black phosphorus production.
The CVT method converts gaseous precursors into solid black phosphorus crystals through chemical reactions, simplifying the operational process and allowing for large-scale production by controlling reaction conditions. Additionally, this method can be conducted at lower temperatures, significantly reducing energy consumption and equipment costs. Therefore, the CVT method has become the mainstream approach for producing high-quality black phosphorus today.

Our company continually innovates in black phosphorus production technology, successfully applying the Chemical Vapor Transport method to achieve efficient and stable black phosphorus production. Below are the key advantages of our technology:
Black Phosphorus Crystal Specifications: We offer a variety of specifications, including 100 mg, 500 mg, 1 g, and 2 g, to meet the needs of different customers. Whether for scientific research or industrial applications, we provide suitable products.
Crystal Size: The lateral size of the black phosphorus crystals is ≥1.0 cm, ensuring good material integrity and operability. This size enhances the practical value of black phosphorus in real-world applications.
Crystal Purity: Through stringent process control, the purity of the black phosphorus crystals reaches ≥99.5%, guaranteeing excellent performance. High-purity black phosphorus performs better in high-tech fields such as electronics and optoelectronics.
Crystal Appearance: Black phosphorus crystals have a black color with a metallic luster, reflecting a high-quality crystal structure. The excellent appearance not only indicates high purity but also reflects the high crystallization quality of the black phosphorus.
Crystal Growth Method: Utilizing the Chemical Vapor Transport (CVT) method, we efficiently produce black phosphorus under ambient pressure and lower temperatures, significantly improving production efficiency and product quality. Compared to traditional methods, the CVT method is more environmentally friendly and cost-effective.
Packaging: To protect product stability, we use vacuum or inert gas protection packaging, ensuring that black phosphorus is not affected by oxidation and moisture during transportation and storage. This packaging method extends the product’s shelf life, ensuring that users receive black phosphorus of the highest quality.

In addition, our black phosphorus products have been validated through various characterization techniques, including X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS) analysis. The XRD results demonstrate that our black phosphorus crystals possess high crystallinity, SEM images reveal the crystal morphology of black phosphorus, and EDS analysis confirms its high-purity composition.
These characterization techniques not only ensure the high quality of our black phosphorus but also enable us to provide customers with detailed technical support and data reports, helping them better understand and utilize our products.
Thanks to our advanced production technology, the high-purity black phosphorus we produce has already been widely applied in multiple fields:
