A method for the joining of ceramic pieces with a hermetically sealed joint comprising brazing a layer of joining material between the two pieces. The wetting and flow of the joining material is controlled by the selection of the joining material, the joining temperature, the joining atmosphere, and other factors. The ceramic pieces may be on a non-diffusable type, such as aluminum nitride, alumina, beryllium oxide, and zirconia, and the pieces may be brazed with an aluminum alloy under controlled atmosphere. The joint material is adapted to later withstand both the environments within a process chamber during substrate processing, and the oxygenated atmosphere which may be seen within the shaft of a heater or electrostatic chuck.

The first connection portion includes a first lead electrode connected to the first internal electrode, and the second connection portion includes a second lead electrode connected to the second internal electrode.

A green body part comprises a first green portion, a second green portion, an interfacial joint between the first green portion and the second green portion, and a joint material disposed within the interfacial joint. The joint material comprises a powder having a particle size distribution than or equal to 1 m and less than or equal to 50 m. A method of manufacturing a joined part includes applying a joint material on a face of the first green portion and contacting the second green portion to the joint material on the face of the first green portion to form a joined green body part.

A crucible includes an outer element and an inner element. The outer element includes a first portion that is horizontal at a bottom end of the crucible and a second portion that ascends radially outwardly from the bottom end of the crucible to a top end of the crucible at a first acute angle to a vertical axis. The inner element includes a conus with a cylinder at a base of the conus. The conus descends radially outwardly from the top end of the crucible to the bottom end of the crucible at a second acute angle to the vertical axis. The inner element includes a base portion of the cylinder attached to the first portion of the outer element using a sealant to form a hollow mold between an inner portion of the outer element and an outer portion of the inner element.

A method for joining an optical part made of quartz glass and a supporting part made of ceramic includes forming a metal layer on a surface of the supporting part by electroless plating, polishing the formed metal layer with a polishing pad to form a first smoothed face on the supporting part surface, polishing a surface of the optical part with the polishing pad to form a second smoothed face, cleaning the first smoothed face and the second smoothed face with ultrasonic cleaning water, forming a first metal film on the first smoothed face by vapor deposition and forming a second metal film on the second smoothed face by vapor deposition, and joining the first metal film and the second metal film to each other by interatomic joining by atomic diffusion between the faces at which the first metal film and the second metal film contact with each other.
