Product description
Polynitrogen silane series products are ternary (SiCN) ceramic precursors that are different from the binary (SiC) ceramic precursor polycarbosilane. The diversity of elements leads to the diversity of compositions, and the diversity of compositions brings high-temperature stability. The series of solid polynitrogen silane products produced by our company are currently the only products in China that have been mass-produced.
Product performance
It cannot evaporate because of the strong hydrogen bonding between molecules. Can bond with most substrates to form chemical bonds. In the temperature range of 100-300°C, cross-linking occurs between molecules and can be transformed into a transparent hard plastic. In the temperature range of 400-700°C, the organic groups on the molecules decompose, accompanied by the escape of small hydrocarbon molecules, ammonia, and hydrogen. In the temperature range of 700-1200℃, a three-dimensional amorphous network structure is formed, called SiCN ceramic, with a density of ~2 g/cm3. Above 1500℃, a Si3N4/SiC crystal phase is formed, with a density of ~3g/cm3
Product Usage:
1. As a precursor of advanced ceramics, used to prepare ceramic matrix composite materials, ceramic fibers, ceramic coatings, ceramic porous materials, and ceramic films;
2. As an organic resin, it is used to prepare high-temperature-resistant, flame-retardant, high-strength engineering plastics and organic glass bodies, and is used for corrosion-resistant, anti-graffiti, and friction-resistant coatings;
3. As an adhesive, used for high-strength bonding of all materials themselves and each other, including metal, ceramics, glass, plastic, rubber, wood, stone, cement, fiber, cloth, etc.;
4. As porous materials, prepare macroporous, mesoporous and microporous materials for catalyst support and heat insulation.
