Chemical Industry
High-temperature chemical plants stress refractories and internals with rapid cycling, aggressive atmospheres, and long campaigns—exactly where SiC kiln furniture and structural SiC earn their place alongside catalyst supports that must survive hot gas and abrasion. Carbon additions also matter when processes need a dependable reducing carbon or electrode-grade carbon quality, not just bulk fuel. We supply SiC and carbon grades matched to those service modes so uptime and batch repeatability stay anchored in material choice.
Application Overview
Carbon & Alloy Solutions for Chemical
Silicon carbide is widely used where ceramics see simultaneous heat, corrosive atmospheres, and thermal shock—kiln furniture, setter plates, and furnace hardware operating from roughly 1,200 °C up through the highest practical firing regimes depend on SiC’s thermal shock resistance and hot strength. In fixed- and fluidized-bed units, SiC-based media and supports can stabilize temperature distribution and withstand erosive flow when catalyst carriers must last whole campaigns. Carbothermic and high-temperature reductions also draw on high fixed-carbon materials when a controlled carbon source is part of the chemistry. For carbon electrodes and conductive carbon forms, low ash and consistent real density support electrical and process predictability. Our SiC, CAC, and GPC lines map to refractory structure, reduction chemistry, and conductive carbon needs in chemical and materials plants.
Industry Challenges
