Oxidized Polyacrylonitrile Fiber is produced by solution spinning and then processing through a high temperature oven, in air, to stabilize the molecular structure.
2.
There are a total of 26 platinum ovens to heat samples 10 medium temperature ovens at and 16 high temperature ovens at and one oven to clear the drill bit for reuse.
3.
To remove the oxide, Davisson and Germer heated the specimen in a high temperature oven, not knowing that this affected the formerly polycrystalline structure of the nickel to form large single crystal areas with crystal planes continuous over the width of the electron beam.
