The present invention is a method for producing a light-emitting body containing silicon fine particles that emit visible light, comprising: a baking step of baking a mixture containing a silicon source and a carbon source in an inert atmosphere; a rapid cooling step of rapidly cooling a gas generated by baking the mixture to obtain a composite powder; and a removing step of removing a portion of the composite powder, wherein in the removing step, a portion of silicon monoxide and a portion of silicon dioxide are removed from the composite powder containing silicon fine particles, silicon monoxide, and silicon dioxide.

A liquid mixture is prepared by using a liquid phenolic resin (PL-2818) serving as a carbon source. While an inert gas is introduced into the liquid mixture, a released gas is discharged. Then, the liquid mixture is dried in a reduced-pressure atmosphere, and thereby the nitrogen dissolved in the liquid mixture can be reduced. In this way, the amount of nitrogen content after burning can be reduced.

An object and project of the present invention is to provide a method for producing silicon fine particles and a method for controlling a particle diameter of silicon fine particles which enable efficient production of silicon fine particles having a uniform particle diameter. A the characteristics of the present invention is producing silicon fine particles having a smaller particle diameter than silicon particles and controlling a particle diameter of silicon fine particles by immersing the silicon particles into an etching solution and irradiating the silicon particles immersed in the etching solution with light having a larger energy than a band gap energy of the silicon particles.

A strong silicide joint between silicon carbide and a metal is resistant to fracture even at high temperature. A method for manufacturing the silicide joint is also provided. This method includes the steps of: bringing a silicon carbide-based member into contact with a Kovar (Fe&#x2014;Ni&#x2014;Co alloy) member; and thermally joining the silicon carbide-based member to the Kovar member.
