| 简介 |
The present invention refers to magnetic chain synthesis reaction by high strength porous silicon nitride ceramics manufacturing method and manufacturing method in the second 30-50% porosity produced by 60 MPa or more porous silicon nitride ceramics the burglar getting broken off relates to manufacturing method.
The present invention refers to the powder of mixing a powder silicon nitride and silicon powder for negative electrode material of step of manufacturing a mixture, said powder mixture to a pressure molding step of manufacturing a the body, said molded body and a high-pressure a nitrogen ambient under the magnetic chain synthesis reaction, a steps : cooling the ceramic manufacture ceramics of silicon nitride porous including a method and LCD manufactured by this method provides porous silicon nitride ceramic.
According to the present invention, a nitrogen ambient under high pressure atmospheres of 10-70 at room temperature within a few minutes to a modem porous ceramic by a manufacturing process time and the amount of, substantially free from energy dissipation in, expensive rare earth metal oxide such as generated in the sintering auxiliary copyright 2000. |
