JGC has filed a patent for a method of manufacturing a sintered body using laser irradiation. The method involves providing a raw material containing ceramic powder and a laser absorbing oxide, forming an article from the raw material, and sintering the article with a laser to create a sintered portion. The laser absorbing oxide has an absorption rate at a laser wavelength higher by 5% or more than that of the ceramic powder.

Method for manufacturing a sintered body using laser irradiation
A recently filed patent (Publication Number: US20230191652A1) describes a method for manufacturing a sintered body using laser irradiation. The method involves several steps, including providing a raw material containing a ceramic powder and a laser absorbing oxide, forming an article from the raw material, and sintering the article with a laser to create a sintered portion.
In the article forming step, the ceramic powder and laser absorbing oxide can be mixed and molded into an article shape, or the ceramic powder can be molded into an article shape and then the laser absorbing oxide can be applied to the surface. The laser absorbing oxide used in the method can be magnesium oxide or a rare earth element-containing oxide, such as yttrium oxide.
The ratios of the laser absorbing oxide and ceramic powder in the raw materials are specified to be between 1% and 65% by mass for the laser absorbing oxide, and between 35% and 99% by mass for the ceramic powder. The sintering step can be performed using various types of lasers, including Nd: YAG, Nd: YVO, Nd: YLF, titanium sapphire, and carbon dioxide lasers.
The sintered portion can be formed either in an air atmosphere or in a non-oxidizing atmosphere followed by further laser irradiation in an air atmosphere. Additionally, the patent mentions a specific method for obtaining black yttrium oxide as the laser absorbing oxide, which involves irradiating white yttrium oxide with a laser in a non-oxidizing atmosphere.
The ceramic powder used in the method can contain aluminum oxide, aluminum nitride, or aluminum oxynitride, or a combination of these materials.
Overall, this patent describes a method for manufacturing a sintered body using laser irradiation, with specific steps and parameters for the raw materials, article formation, sintering, and laser types. The inclusion of a laser absorbing oxide with a higher absorption rate than the ceramic powder allows for efficient sintering. The method offers flexibility in terms of the atmosphere used during sintering and provides a specific technique for obtaining the laser absorbing oxide.
