Are you looking for a harder BN ceramic? If so, our BSC material will be a kind of good choice.
The pure Boron Nitride ceramic like 99% BN and 99.7% BN is very soft and easy to be broken during the process of using, which is a headache problem. To solve its easy-broken issue and meet the user’s extremely harsh operating conditions, our design team have worked out a new material BSC BN+SiC. It is the BN composited with Silicon Carbide ceramic.With silicon carbide combined in, it makes the compressive strength 175MPa, while the pure BN is only 45MPa for 99.7% and 85MPa for 99%. At the same time, the tree -point bending strength is more than double in value.

This is a material developed by Innovacera technical team. It has a good performance in compressive and bending strength, as well as electrical insulation and low thermal expansion coefficient so it can be used in precision engineering applications and extreme environment like metals refining, electronics, semiconductor, clean energy industry and vacuum furnace.
For application, it is suitable for max temperature 1800 degree centigrade for a long time with inactive gas or under vacuum environment. At atmosphere, the max working temperature is 900 degree centigrade. Below is the detail material properties of BSC BN+SiC ceramic:
| Material Composition | Boron Nitride, Silicon Carbide |
