Silicon Carbide Microreactor

The Silicon Carbide Microreactor is pressureless-sintered silicon carbide, sealed in one piece rather than bolted with gaskets, so it seals reliably, resists corrosion and does not fatigue from repeated assembly. Without added free silicon it resists almost all chemicals (class A, comparable to PTFE), and it conducts heat at 160 W/m·K.

It suits processes that glass and metal reactors cannot handle: fluorine chemistry (corrosion below 0.04 mm per year), strong bases, reactions releasing over 200 kJ/mol, and small- and pilot-scale work with hazardous chemicals. Throughput can be made to order.
