As Southeast Asia's largest economy, Indonesia is experiencing rapid industrial expansion — driving surging demand for high-performance mullite refractory bricks across multiple sectors.
Indonesia's steel production capacity has grown significantly with major projects in East Kalimantan and Java, requiring large volumes of mullite bricks for blast furnaces, ladles, and electric arc furnaces operating above 1600°C.
With massive infrastructure investment under the National Strategic Projects program, Indonesia's cement industry — home to giants like Semen Indonesia — demands reliable kiln linings where mullite bricks provide superior thermal stability and low thermal conductivity.
Pertamina's downstream refinery expansions and new petrochemical complexes in Banten and East Java require advanced refractory solutions capable of withstanding corrosive atmospheres and thermal cycling.
Indonesia's growing glass container and flat glass industry, concentrated in Tangerang and Surabaya, relies on mullite and zircon-mullite bricks to line regenerators and furnace crowns for continuous high-temperature operation.
Indonesia holds the world's largest nickel reserves. The rapid expansion of RKEF (Rotary Kiln Electric Furnace) smelters in Sulawesi and Maluku — fueled by EV battery demand — creates immense demand for high-alumina mullite refractories in rotary kilns and electric furnace linings.
As Indonesia advances its renewable energy targets, new waste-to-energy and biomass power plants require chemically resistant refractory linings, where mullite bricks' excellent alkali resistance provides a decisive advantage.
Zhengzhou SK Refractory Co., Ltd. (SK) is located in Xinmi, Zhengzhou, China. For over twenty years, SK Refractories has been dedicated to delivering high-performance, reliable solutions that redefine durability and efficiency for clients worldwide.

From Sulawesi nickel smelters to Surabaya glass plants, our mullite refractory bricks are engineered for Indonesia's most demanding high-temperature environments.
Mullite bricks line the rotary kilns and electric furnace roofs in RKEF operations, providing excellent resistance to slag erosion, thermal shock, and temperatures exceeding 1550°C in Indonesia's booming nickel processing zones.
Indonesia's cement producers rely on mullite bricks for transition zone and cooling zone linings, where their low thermal conductivity reduces fuel consumption and extends campaign life in high-throughput kilns.
Mullite-based refractories are applied in steel ladle linings and EAF roofs at Indonesian steel complexes, offering superior resistance to molten steel and slag infiltration at temperatures above 1600°C.
Zircon-mullite and fused mullite bricks are the material of choice for checker bricks and regenerator crowns in Indonesian float glass and container glass furnaces, ensuring long campaign life and energy efficiency.
In Pertamina's refinery reformer furnaces and cracking units, mullite bricks provide stable performance under cyclic thermal loading and reducing atmospheres, minimizing unplanned shutdowns.
Indonesia's expanding WTE sector requires alkali-resistant refractory linings. Mullite bricks' inherent resistance to potassium and sodium compounds makes them ideal for combustion chambers and boiler linings.
Indonesia is a major ceramics exporter. Mullite kiln furniture and brick linings support high-temperature periodic and tunnel kilns used in ceramic tile, sanitaryware, and technical ceramics production.
Coal-fired and co-firing power plants across Indonesia use mullite castables and bricks in boiler walls and cyclone separators, where thermal stability and abrasion resistance are critical for continuous operation.
The Indonesian refractory market is evolving rapidly. Understanding these trends helps industrial operators make smarter procurement decisions.
Indonesia's ambition to become a global EV battery hub is driving unprecedented investment in nickel processing. The proliferation of RKEF smelters and battery precursor plants is expected to increase mullite refractory consumption by over 30% by 2027 compared to 2022 levels.
Under the RCEP framework and bilateral trade agreements, Chinese refractory suppliers enjoy competitive tariff rates when exporting to Indonesia. This positions SK Refractory as a cost-effective partner compared to European or Japanese alternatives for Indonesian buyers.
Indonesia's industrial decarbonization roadmap is pushing manufacturers to adopt energy-efficient refractory solutions. Mullite insulation bricks with low thermal conductivity directly reduce kiln energy consumption, aligning with government incentives for green industrial transformation.
Indonesian industrial operators are increasingly specifying high-purity mullite (Al₂O₃ >70%) and fused mullite bricks for critical applications, moving away from lower-grade alternatives. SK's advanced sintering technology meets these elevated specifications consistently.
Indonesia's downstream processing ban on raw mineral exports has catalyzed massive investment in smelters, refineries, and chemical plants — all requiring substantial refractory installations. The total addressable refractory market in Indonesia is projected to exceed USD 380 million by 2028.
Indonesian procurement managers are increasingly bypassing trading companies to source directly from Chinese manufacturers like SK Refractory, achieving 15–25% cost savings while gaining access to technical support, custom specifications, and faster lead times.
SK Refractories is well known in domestic markets and abroad for the quality of refractory bricks. The refractory materials produced by SK Refractories have been exported to more than 35 countries including America, Spain, Germany, Italy, Brazil, Belgium, India, Japan, Korea, and increasingly across Southeast Asia including Indonesia.
