Ceramic particles are a type of lightweight aggregate produced through foaming in rotary kilns. They have the characteristics of being lightweight, hard on the outside, porous inside, uniform in shape and composition, and low in density.
They are widely used in building materials, horticulture, green materials, refractory insulation materials, wastewater treatment, and other fields. High strength ceramsite, also known as high-performance lightweight aggregate or high-performance ceramsite, is an artificial lightweight aggregate made from suitable raw materials (such as shale gravel, coal based solid waste, sludge, iron tailings, drilling cuttings, waste incineration fly ash, etc.) and processed through special processes to produce different density grades, high strength, low porosity, and low water absorption.
High strength ceramic particles have the characteristics of low thermal conductivity, low water absorption, high strength, thermal insulation, frost and moisture resistance, sound insulation and earthquake resistance. They are mainly used in the construction industry as aggregates for concrete, blocks, and boards. They can be used to make building materials such as concrete blocks, wall panels, and various prefabricated components, and are further applied in high-rise and large-span construction projects. Except for the construction industry, high-strength ceramic particles are relatively less commonly used in other industries.
In recent years, with the strengthening implementation of national solid waste comprehensive utilization and environmental protection industry policies, as well as the rapid development of the construction industry, especially the rapid growth of consumer demand for PC components (concrete prefabricated components) in the prefabricated construction field, the market size of China's high-strength ceramic particle industry has also continued to grow. According to the "2021-2025 Deep Market Research and Investment Strategy Suggestions Report on High Strength Ceramics Industry", the demand for high-strength ceramics in China has shown a rapid growth trend since 2016. In 2020, the demand for high-strength ceramic pellets in China reached 854500 cubic meters, a year-on-year increase of 6.4%.
Compared to ordinary ceramic particles, high-strength ceramic particles have higher profitability and stronger appeal to investors. Moreover, Chinese researchers have always attached great importance to the research of high-strength ceramic particles, providing technical support for the development of the high-strength ceramic particle industry. Since 2016, the number of enterprises in the domestic high-strength ceramic grain industry has been continuously increasing, and currently there are more than 100 enterprises.
Industry analysts say that high-strength ceramic particles are not only lightweight with low water absorption, but also have a hard surface and good compressive strength. They can replace stones as lightweight and coarse aggregates for cast-in-place lightweight aggregate concrete. They can not only reduce self weight and cost, but also improve building insulation, heat insulation, noise reduction and other performance. Therefore, high-strength ceramic particles have broad application prospects, and lightweight and high-strength ceramic particles are the main development direction of the ceramic particle market in the future. With the continuous development of the industry in the future, more and more enterprises will continue to increase their research and development efforts and market expansion efforts in high-strength ceramic particle technology. The market competition risk in China's high-strength ceramic particle industry will continue to increase. High strength ceramic grain enterprises should conduct comprehensive assessments based on their own strength, formulate detailed industry development plans, and choose appropriate market competition methods.
