There are many types of low-melting glass powders and they have broad application prospects in the photovoltaic field.

Glass powder is an inorganic amorphous hard ultra-fine particle powder. Low melting point glass powder, also known as low-temperature fused glass powder, is a subdivided product of glass powder. It refers to a glass powder produced by melting, copolymerizing and crystallizing in a high-temperature environment using environmentally friendly materials as raw materials. Compared with ordinary glass powder, low melting point glass powder has the advantages of good chemical stability, good insulation, good hue, green environmental protection, and high mechanical strength. It is used in many fields such as flame retardant materials, photovoltaics, coatings, microelectronics, and household appliances. widely.

There are many types of low melting point glass powder. According to different base materials, low melting point glass powder can be divided into boron series low melting point glass powder, lead series low melting point glass powder, vanadate series low melting point glass powder, bismuthate series low melting point glass powder, phosphate series low melting point glass Powder, special low melting point glass powder, etc. Lead-based low melting point glass powder has the advantages of good chemical stability and high insulation resistance. It is the most widely used low melting point glass powder. At present, it has achieved industrial production, and my country’s output has maintained a long-term growth trend.

The main production processes of low melting point glass powder include wet method and dry method. The wet method is suitable for producing nano-level low-melting point glass powder and micro-nano-level low-melting point fibers; the dry method is suitable for producing micron-level low-melting point fibers. Sintering is a key link in the production of low melting point glass powder, and sintering temperature and time play a decisive role in its performance and quality. In recent years, with in-depth research, my country’s low-melting point glass powder sintering process has been continuously optimized, driving its output and quality to further improve.

According to the “2023-2028 China Low Melting Point Glass Powder Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , low melting point glass powder, as a new sealing material, is widely used in many fields. As the concept of green environmental protection continues to deepen, the prosperity of my country’s photovoltaic power generation industry continues to increase. According to statistics from the National Energy Administration, my country’s newly installed photovoltaic power generation capacity will exceed 87.41 million kilowatts in 2022. Low melting point glass powder can be used to manufacture photovoltaic cells, which can effectively improve their photoelectric conversion efficiency. As downstream demand grows, the market space for low melting point glass powder will further expand.

The main manufacturers of low-melting glass powder in my country include Witton Crystal Phosphorus, Anmi Micronano, Lomat Glass, Wohua Company, etc. Anmi Microna’s main products include transparent powder, silica powder, low melting point glass powder and titanium powder, etc. The sales volume of its low melting point glass powders such as N250, D245, FD61 and LX45 ranks among the top in my country.

Industry analysts said that low melting point glass powder has the advantages of good chemical stability and good insulation. As a new type of sealing Materials, market demand continues to grow. my country is the first country to develop low-melting-point glass powder. With the continuous advancement of local enterprises’ technological level, the output and quality of low-melting-point glass powder have been further improved.
