Recently, a novel organoborosilazane precursor polymer named IOTA 9120 has drawn significant attention from the industry. This liquid precursor, composed of repeating Si-N and Si-N-B units, functions both as a thermosetting resin and a ceramic precursor. It enables crosslinking and curing at relatively mild conditions (120–180°C), and can be pyrolyzed into high-performance SiBCN ceramics at elevated temperatures.

IOTA 9120 features low viscosity, multiple curing options, high ceramic yield, and excellent adhesion to metals, ceramics, and graphite. The curing process can be achieved either through thermal treatment or via hydrosilylation catalyzed by platinum, offering great processing flexibility. After pyrolysis at 800°C, the ceramic yield exceeds 50%, with a final ceramic density ranging from 1.70 to 2.00 g/cm³, making it suitable for various high-end applications.

The product is widely used in ceramic matrix composites (CMCs), metal matrix composites, high-temperature adhesives, anti-corrosion coatings, and oxidation-resistant ceramic coatings. Due to its sensitivity to moisture and alcohols, it is recommended for use in dry and well-ventilated environments with appropriate safety precautions.

With its excellent performance and processing versatility, IOTA 9120 offers a promising new route for the development and manufacturing of advanced ceramic materials, with potential applications in aerospace, new energy, and high-end equipment industries.
