Global Silicon Nitride Market Size is Expected to Grow to $234.15 Million by 2029

Global Silicon Nitride Market Overview

According to Global Market Monitor, the global silicon nitride market size was $125.09 million in 2023 and is expected to grow to $234.15 million by 2029.

Silicon nitride is an important structural ceramic material. It is a super hard substance that is inherently lubricious and resistant to wear and is an atomic crystal and resistant to oxidation at high temperatures. Moreover, it can resist thermal shock, is heated to above 1000 ° C in the air, and is rapidly cooled and then heated rapidly without breaking. Because of the excellent characteristics of silicon nitride ceramics, it is often used to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds.

China is the Main Consumption Market.

In recent years, photovoltaic enterprises have grown rapidly in China, and the rapid development has driven the rise of related auxiliary products. For photovoltaics, the auxiliary silicon nitride powder used in the upstream polycrystalline silicon ingot process is very important in the whole ingot process. Silicon wafers are the front products of solar cells, and high-quality silicon ingots are the guarantee of high-quality silicon wafers. Silicon nitride powder plays an important role in the process of polycrystalline silicon ingots. It is sprayed on the inner layer of quartz crucibles. At the time of demolding and blocking the migration of oxygen and other impurity elements into the silicon ingot, the purity of the silicon nitride itself also affects the purity of the ingot and prevents the ingot from cracking, causing crevices and pores during the ingot process. Play a vital role. The rapid development of China's photovoltaic industry has driven the demand for silicon carbide powder in the Chinese market. It is expected that China will become the largest downstream consumer market.

Market Limitations

At present, the production technology of polysilicon materials has long been in the hands of a small number of countries and companies. Form a technical blockade and market monopoly. For potential market entrants, technical barriers cannot be ignored.The research process of silicon hydride powder has invested a lot of manpower and material resources, and the research is costly. Only a small number of enterprises can support the consumption of such funds. And the research on materials, from research to research results to application to the market is a long-term process that requires strong financial support.
