Process for producing silicon carbide ceramic micro tube with thin wall |
| abstract |
An improved process for producing a silicon carbide ceramic micro tubes (SiC micro tube) from a silicon-based polymer fiber by applying an ionizing radiation such that the surface part of the fiber selectively undergoes oxidative crosslinking, extracting the uncrosslinked core part of the fiber with an organic solvent to form a hollow fiber, and firing it in an inert gas is characterized by using a polymer blend of polycarbosilane and polyvinylsilane as the silicon polymer or applying the ionizing radiation to the silicon-based polymer fiber as it is cooled. The two methods may be performed either individually or in combination to produce tubes with their wall thickness controlled at a desired value in the range of 2-10 μm although this has been impossible to achieve in the prior art. |
