The 69th International Colloquium on Refractories (ICR 2026) kicked off at September 16, 2026, running through September 17 in Aachen, Germany. As a landmark global conference for high-temperature engineering, industrial ceramics, and furnace technology, ICR 2026 gathers research scholars, refractory manufacturers, and industry leaders from around the globe. HUAO is actively participating in this prestigious international event, featuring its complete high-performance raw material ecosystem—including alumina micro-powder, tabular alumina, white fused alumina, mullite, and specialized magnesia products. Facing heightened global demands for energy efficiency, reduced CO₂ emissions, and longer lining service life in high-temperature kilns, plant operators are increasingly relying on high-purity synthetic aggregates. Our presentation at ICR 2026 focuses on how integrated raw material selection directly improves the thermal stability, mechanical load-bearing capacity, and corrosion resistance of modern refractory products. Unifying Alumina Powders and Tabular Alumina for Matrix Stability This exhibition we highlight the synergy between its low-sodium calcined alumina micro-powders and high-density tabular alumina aggregates. Processed through advanced micro-grinding, Our alumina powders achieve an alpha-phase crystalline conversion rate of α-Al₂O₃ ≥ 93% to ≥ 94%, with soda impurities tightly controlled (Na₂O ≤ 0.15% in high-purity series). These reactive powders optimize particle packing within low-cement and ultra-low cement castables, enabling lower mixing water requirements and accelerating liquid-phase sintering during initial heat-up. Working in combination with the micro-powder matrix, tabular alumina serves as a ultra-pure corundum aggregate (Al₂O₃ ≥ 99.2%, Bulk Density ≥ 3.5 g/cm³, Porosity ≤ 5.0%). Produced via high-temperature sintering without external additives, its closed intra-crystalline pore structure delivers excellent resistance to severe thermal shock and slag erosion. This combination is particularly suited for high-stress steelmaking components, such as ladle purging plugs, sliding gate plates, and continuous casting nozzles. Expanding Options with White Fused Alumina, Mullite, and Magnesia To support diverse refractory formulations across different temperature zones and chemical environments, HUAO is showcasing several products: White Fused Alumina (WFA): Electro-fused from high-purity alumina at extreme temperatures, providing high hardness, high density, and low iron contamination for premium shaped refractory bricks and abrasive applications. Mullite Grains: Engineered for superior creep resistance and volume stability under continuous thermal loading, making them an optimal choice for hot-blast stove linings, glass furnace checkers, and ceramic kiln furniture. High-Purity Magnesia Series: Formulated to withstand aggressive basic slag and alkaline environments in steelmaking ladles, non-ferrous smelting furnaces, and cement rotary kilns. Quality Control and Technical Support Partnerships Operating as an integrated manufacturer and exporter, we implement strict ISO-certified quality management protocols across all processing steps. Every batch of raw materials is verified for chemical composition, grain size distribution, and density to ensure stable performance in international refractory formulations. HUAO warmly welcomes engineers, procurement specialists, and industrial partners attending ICR 2026 in Aachen to meet with our technical team, explore custom grain size preparations, and discuss long-term supply solutions.

ZIBO HUAO NEW MATERIALS CO., LTD. will showcase its full spectrum of high-temperature raw materials at the International Colloquium on Refractories - ICR 2026, held from September 16 to 17, 2026, in Aachen, Germany. Operating as an integrated manufacturing exporter, HUAO will present its high-purity reactive alumina, tabular alumina, calcined alumina, white fused alumina, fused mullite, and specialized magnesia products to global steelmaking, cement, and glass refractory engineering teams. The International Colloquium on Refractories - ICR 2026 serves as one of Europe's premier technical platforms for high-temperature materials engineering. Bringing together plant managers, furnace designers, and procurement directors from across the steel, foundry, and petrochemical sectors, the 2026 event focuses on sustainable furnace linings, thermal shock stability, and slag resistance in high-stress processing equipment. During the exhibition, HUAO will highlight its core high-performance raw material series engineered for unshaped refractory castables, slide gate plates, steel ladles, and tundish systems: Reactive & Calcined Alumina: Made from low sodium calcined alumina powder through grinding and deep processing. Tabular Alumina: Fully densified sintered alpha-alumina produced without sintering aids, delivering low open porosity and exceptional volume stability under thermal shock. White Fused Alumina: Electrically fused above 2000°C from pure calcined alumina, providing high hardness and high temperature oxidation resistance. Fused Mullite: It is manufactured by melting high-purity bauxite and silica raw materials at ultra-high temperature electric arc furnace, then cooling, crushing, grinding and screening strictly. Dead Burned Magnesia: Sintered in high-temperature kilns (1400°C - 1800°C) from natural magnesite ore (46% content), yielding an economical 85%-92% MgO base for basic refractory formulations. Fused Magnesia & Large Crystal Fused Magnesia: Fused in electric arc furnaces from caustic calcined or high-purity light magnesia powder, offering superior corrosion resistance against aggressive basic slag. We cordially invite international partners, refractory material manufacturers, and casting engineers to meet at booth 22 of ICR2026 in Aachen. Attendees can evaluate the technical parameter table and arrange stable long-term supply agreements for win-win cooperation.
