SIALON MARKET OVERVIEW

The global Sialon Market is poised for significant growth USD 1.97 billion in 2025, and projected to reach USD 2.44 billion by 2034, with a CAGR of 2.71% from 2025 to 2034.

The United States Sialon market size is projected at USD 0.59 billion in 2025, the Europe market at USD 0.56 billion, and the China market at USD 0.52 billion.

Sialon is a specific class of high temperature refractory materials that have high strength and high temperature. They are known for their properties such as thermal shock resistance, high temperature, creep resistance, fracture toughness, and moderate wear resistance. They have extreme corrosion resistance and are used in the chemical industry. It is formed by combining silicon nitride, alumina, alumina nitride, yttrium, and silica. They can be made into different shapes at a very high temperature of 1200 degree centigrade.   

The growing demand for sialon from the chemical industry is attributed to its properties. They are also used in the metal industry in non-ferrous molten metals especially aluminum and alloys such as metal feed tubes for burner, aluminum die casting, immersion, injector, and heater tubes for non-ferrous metals. The demand for sialon is also derived from chemical and process industries and oil & gas industries owing to its chemical stability and corrosion and wear resistance properties.

KEY FINDINGS

COVID-19 IMPACT

Restriction on Various Industries to Hamper Market Growth

The effects of the COVID-19 pandemic are already being felt on a global level, the global sialon market was significantly influenced. The outbreak of COVID-19 had a negative impact on several markets. Various countries went into lockdown. With sudden pandemic, all kinds of businesses observed disruptions. With many restrictions in the pandemic, different types of markets were negatively impacted. Restrictions on various industries impacted the demand for various industries such as metal, chemical and process, and advanced ceramics industries. Halt on the operations in various industries affected the demand for sialon simultaneously. It created a gap in supply and demand due to shortage of labor and also affected logistics.      

LATEST TRENDS
