Electro cast zircon blocks, offering superior resistance to high temperatures and chemical attack, are zirconia (ZrO₂)-based materials that provide excellent protection against glass corrosion, especially in glass melting furnaces. Their high density and low porosity ensure long-lasting performance and enhance structural stability within the furnace.

The zircon blocks produced by Termoref maintain their dimensional stability even at elevated temperatures and support energy efficiency. Used in the glass, steel, and ceramics industries, these blocks extend furnace service life thanks to their resistance to thermal shock. Our company manufactures reliable refractory solutions with customized dimensions, compositions, and quality options for each project.
