Title:
セラミック光透過性障壁セルを製造する方法及びその方法によって製造される障壁セル
Document Type and Number:
Japanese Patent JP6596420
Kind Code:
B2
Abstract:
A method 100 of manufacturing a ceramic light transmitting barrier cell for enclosing a luminescent material and such a ceramic light transmitting barrier cell are provided. A part of a pre-formed barrier cell is formed 102 by providing a material mix comprising a binder and inorganic particles in a first mold. On the part is provided 104 a sacrificial layer for defining a cavity. A remainder part of the pre-formed barrier cell is formed 106 by providing the material mix in a second mold which already comprises the part with the sacrificial layer. The sacrificial layer is at least partially removed 112 to obtain the cavity. Optionally, the pre-formed barrier cell is heated 114, 116 (and/or sintered) to obtain the ceramic light transmitting barrier cell. The method 100 of manufacturing is suitable for producing at large scale relatively cheap and accurately formed ceramic light transmitting barrier cells.
