| Product performance | High activity | Medium activity | low activity | |
| It is easy to oxidize and cross-link in the air, and it is easy to spontaneously ignite when exposed to flammable substances. |
Oxidation and heat in the air form a highly active oxide film | It will slowly oxidize in the air and form a protective film | It will slowly oxidize in the air and form a protective film | |
| usage | High activity, mainly used as raw material for the production of low-activity silicon carbide ceramic precursors and composite ceramic precursors: such as the preparation of metal-based composite ceramic precursors such as oxygen-free zirconium/hafnium/tantalum, and special silicon carbide ceramic-based modified composite materials wait. | Medium activity, often used in combination with DVB, used in PIP process carbon ceramic composite materials/friction materials, graphite ceramic functional materials, silicon carbide functional ceramic materials, etc. The ceramic yield is high, the process is mature and stable, and it needs to be stored and used in an oxygen-isolated environment. | Low activity, good stability, slightly high viscosity, ceramic products are mainly silicon carbide; mostly used to prepare high-performance carbon ceramic composite materials/friction materials, graphite ceramic functional materials, silicon carbide functional ceramic materials, silicon carbide fiber reinforced composite materials; resistant High temperature antioxidant coatings, etc. | It has low activity, low viscosity and good stability. The ceramic product is silicon carbide, which can be used to prepare carbon ceramic composite materials/friction materials, graphite ceramics, silicon carbide functional ceramic materials, etc. |
| Precautions For Use | The product is very reactive. It is easily oxidized in the air and emits a lot of heat. It can cause spontaneous combustion when it comes into contact with combustible materials such as cotton, paper scraps, plastics, non-woven fabrics, and nylon. After combustible materials come into contact with this product, they must be immediately placed in a sealed container protected by nitrogen. Store, or cover with fire sand or fire blanket and isolate from surrounding combustible materials, and finally incinerate. | This product is moderately active and can oxidize when exposed to the air, releasing a certain amount of heat and causing the burning of combustibles; combustibles that come into contact with this product should be stored in isolation from oxygen and handled uniformly. | This product has low activity and can slowly oxidize when exposed to air. After long-term exposure to air, an oxidation protective film will form on the surface; combustible materials that come into contact with this product should be stored in isolation from oxygen. | |
