Abstract
A ceramic sheet includes a first surface, a second surface opposite the first surface, and a pair of parallel edges extending therebetween. A thickness of the ceramic sheet is defined between the first and second surfaces, a width of the ceramic sheet is defined between the pair of parallel edges, and a length of the ceramic sheet is defined as a dimension orthogonal to both the thickness and the width. The thickness is less than or equal to 100 μm, the length is greater than or equal to 10 m, and the width is less than or equal to 12 mm. The ceramic sheet has a grain size of less than or equal to 0.2 μm and a porosity of less than or equal to 5%.

A method of cutting a ceramic sheet, the method comprising:
- conveying a ceramic sheet wound around a first spool from the first spool to a second spool, the ceramic sheet comprising a first surface, a second surface opposite the first surface, and a pair of parallel edges extending therebetween, a thickness of the ceramic sheet being defined as a distance between the first and second surfaces, a width of the ceramic sheet being defined as a distance between the pair of parallel edges, and a length of the ceramic sheet being a dimension orthogonal to both the thickness and the width, wherein the thickness of the ceramic sheet is less than or equal to 100 μm, the length of the ceramic sheet is greater than or equal to 10 m, and the width of the ceramic sheet is greater than 12 mm;
- and
- creating a first slit in the ceramic sheet to form a first section and a second section, wherein:
- the first slit extends along the length of the ceramic sheet, and
- the first section has a thickness less than or equal to 100 μm, a length greater than or equal to 10 m, and a width less than or equal to 12 mm.
A method of cutting a ceramic sheet, comprising the steps of:
- loading a ceramic sheet wound around a first spool on a rotary stage configured to rotate the first spool about its central axis, the ceramic sheet comprising a first surface, a second surface opposite the first surface, and a pair of parallel edges extending therebetween, a thickness of the ceramic sheet being defined as a distance between the first and second surfaces, a width of the ceramic sheet being defined as a distance between the pair of parallel edges, and a length of the ceramic sheet being a dimension orthogonal to both the thickness and the width, wherein:
- the thickness of the ceramic sheet is less than or equal to 100 μm, the length of the ceramic sheet is greater than or equal to 10 m, and the width of the ceramic sheet is greater than 12 mm;
- and
- creating, using the cutting tool, a first slit on the ceramic sheet to form a first section and a second section, wherein:
- the first slit extends along the length of the ceramic sheet, and
- the first section has a thickness less than or equal to 100 μm, a length greater than or equal to 10 m, and a width less than or equal to 12 mm.
