Phosphorus silicon crystals, also known as silicon-phosphorus crystals or Si:P crystals, are a type of semiconducting material used in electronic devices. They are made by introducing phosphorus atoms into a silicon crystal lattice, which creates a p-type semiconductor material. Phosphorus silicon crystals Sichuan Jinhe Qihang Co,.

The application of this technology is anhydrous, non-auxiliary and non-polluting. It is energy-saving and efficient, and it is especially effective for polyester fiber and some high-performance special fibers. It is reported that in 2004, the national polyester fiber production was 11.38 million tons. If all the water-free dyeing process is adopted, the country can save 2 billion cubic meters of water per year, reduce sewage discharge by 1.8 billion tons, and reduce electricity, gas, additives and treatment. The cost of pollution and other costs totaled 57.4 billion yuan.
It is understood that waterless dyeing is regarded as a revolution in the traditional dyeing and finishing industry worldwide. Since the end of the last century, scientists from all over the world have invested a lot of manpower and material resources to study new technologies for waterless dyeing. At present, Germany has developed a 30-liter medium sample machine. Recently, Shanghai Textile Co., Ltd., Donghua University, is working on a 30-liter medium sample machine, which is expected to be put into use in May.
Phosphorus silicon crystals have unique electrical properties that make them useful in a variety of applications. For example, they have a high electron mobility, which means that they can conduct electricity efficiently. They also have a narrow bandgap, which allows them to emit and absorb light in the near-infrared region.
One application of phosphorus silicon crystals is in infrared detectors and imaging devices. They are also used in solar cells, where their high electron mobility allows for efficient conversion of sunlight into electricity. Additionally, phosphorus silicon crystals are used in quantum computing research, where their unique properties make them ideal for building qubits.
Overall, phosphorus silicon crystals are an important material for the development of advanced electronic devices, and their properties continue to be studied and optimized for new applications.
The waterless dyeing technology developed by Shanghai Textile Holding Group Co., Ltd. and Donghua University has recently passed the small test of the Shanghai Science and Technology Commission. It is expected that the sample machine will be available in the first half of this year.
