99.99% Ceramic yakaomeswa nano-aluminium

1. Nekuda kweiyo superplasticity ye nano-alumina powder, inogadzirisa zvikanganiso zvemashandisirwo emhando inogumira nekudzika-tembiricha brittleness. Pakati pavo, nano-aluminium oxy-carbide (SiC) nanocomposites ndiyo inonyanya kuzivikanwa, uye simba ravo rekushandura rinobva kuThe single-phase alumina ceramics yakawedzera kubva ku300-400 MPa kusvika ku1 GPa, uye kuoma kwekuputsika kwezvinhu kwakawedzera nezvimwe. kupfuura 40%.

2. Thermal stability: Kuwedzerwa kwe nano-alumina kune ceramic substrate haisi kungovandudza sintering ye substrate, asiwo inovandudza zvakanyanya kugadzikana kwekushisa kwealumina substrate zvinhu, uye kugadzikana kwekushisa kunovandudzwa ne2-3 nguva.

3. Density: Mukugadzira poda extrusion molding, nano-α-Al2O3 powder inogona kuzadzwa mumapores e micron alumina powder, iyo inoderedza kukura kwepore; iyo yekuumba inomanikidza inowedzera, uye nhamba ye pores inogona kuderedzwa, nekudaro ichivandudza Iyo density ye ceramic embryos inovandudza density uye mechanical zvimiro zvealumina ceramics mushure mekupisa.

4. Kuderedza kupisa kwekupisa: kuwedzera kwe nano-a-Al2O3 kunokurudzira basa rekupisa uye kunobatsira kuderedza kupisa kwekupisa. Kana sintering tembiricha iri 1450 ° C, iyo inoshanduka simba uye kuomarara kwekutsemuka kunosvika pakakwirira.

5. Kuwedzerwa kwechikamu chiduku che nano-a-Al2O3 chinogona kunyatso kuvandudza maitiro emagetsi ezvinyorwa. Iyo alumina ceramic inopiswa pa1450 ° C. Kana iyo yekuwedzera iri 10%, iyo flexural simba i415 mPa uye kuomarara kwekutsemuka kuri 4.1 MPa · m^1. /2.
