Keywords: inert ceramic balls, ceramic balls of the catalyst carrier.
They are mainly used in the oil, chemical industries, fertilizer production, natural gas, environmental protection and other industries. It acts as a sealing ball of the column.
Inert ceramic balls are the most widely used carriers in the world because of their excellent consistency and reliability. Products that meet these specifications are made of very high quality chemical-porcelain clay materials that have high mechanical strength and resistance to thermal shock, which makes them an ideal choice for supporting all types of catalysts.
