Ceramic foams are versatile materials with properties like chemical inertness, thermal shock resistance, and high-temperature stability. However, their relatively high cost of realisation has been one of the bottleneck in their wide adoption. With the advent of ceramic precursors, especially the low-cost class like siloxanes and borosiloxanes, new opportunities evolve in developing cost-effective ceramic foams from these precursors. The thesis explores some innovative methods to realize SiBOC ceramic foams with methylvinylborosiloxane as a precursor. The techniques utilized include using melamine foam as scaffolds, urea crystals as sacrificial templates, carbon fiber embedding through natural cotton fibers, and aluminosilicate wool as preform. These foams exhibit low density, tunable porosity, and oxidation resistance up to 1300°C, and have the potential for use in thermal protection applications, including re-entry vehicles.
