Vacuum Freeze Drying Technology For Which Application In Materials Science
Apr 19, 2016

the low-pressure, low-temperature casting manufacturing ceramic and metal products. For ceramic or metal products of low temperature low voltage note die manufacturing method, will contains inorganic sintering particles, and non-water-soluble liquid carrier and dispersed agent of mud, Yu 6.89x106Pa pressure Xia injected specific shape closed die in the, then cooling to carrier of solidification points following formed solid block, again in must temperature and pressure Xia sublimation dry, shortly thereafter in below at room temperature Xia sintering get products, which business have of products composition uniform, and surface smooth, and micro-hole structure dense uniform, and precision high, Relevant information also cited four rotor engine instances on the manufacturing process.
