Kukonzekera ndi katundu wa silicon carbide ceramics ndi reaction sintering

Silicon carbide (SiC) ndi covalent compound yopangidwa ndi kaboni ndi silicon ndipo imadziwika ndi zinthu zake zabwino kwambiri, kuphatikiza kukana kuvala kwambiri, kukana kutenthedwa kwa kutentha, kukana kwa dzimbiri komanso kutsika kwamafuta kwambiri. Zinthu izi zimapangitsa silicon carbide kukhala chinthu choyenera kugwiritsidwa ntchito mosiyanasiyana m'mafakitale angapo, kuphatikiza zakuthambo, kupanga makina, mafuta a petrochemicals, kusungunula zitsulo ndi zamagetsi. Makamaka oyenera kupanga mbali kuvala zosagwira ndi mkulu-kutentha structural zigawo. Kupanga zinthu zopangira sintered silicon carbide ceramics kwathandizira kwambiri kupititsa patsogolo ntchito zamafakitale zazinthu zosunthikazi.

Njira yachikhalidwe yopangirareaction-sintered silicon carbide ceramicsndi kugwiritsa ntchito silicon carbide ufa pamodzi ndi pang'ono mpweya ufa. Chosakanizacho chimakhala ndi kutentha kwambiri kwa siliconization kuti apange zinthu zowuma za ceramic. Komabe, luso lakale limeneli lili ndi zovuta zake. Njira yopangira sintering imadziwika ndi nthawi yayitali, kutentha kwambiri komanso kugwiritsa ntchito mphamvu zambiri, zomwe zimapangitsa kuti pakhale ndalama zambiri zopangira. Pamene zofunikira zamafakitale zamawonekedwe ndi mawonekedwe a silicon carbide ceramic zikuchulukirachulukira, zoperewera za njira zachikhalidwe zimawonekera kwambiri.

M'zaka zaposachedwa, kukhazikitsidwa kwa silicon carbide nanopowders kwakhala njira yodalirika yosinthira makina a silicon carbide ceramics. Kugwiritsa ntchito nanopowder kumatha kupanga zoumba zokhala ndi kachulukidwe kakang'ono kwambiri komanso mphamvu zosinthika kwambiri. Komabe, mtengo wa silicon carbide nanopowder ndi wokwera kwambiri, nthawi zambiri umaposa 10,000 yuan pa tani, zomwe zimalepheretsa kufalikira kwa anthu komanso kupanga kwakukulu. Vuto lazachuma limeneli limafuna kufufuza kwa zipangizo zina zopangira ndi njira zopangira zitsulo za silicon carbide ceramics kukhala zotheka komanso zotsika mtengo.

Kuphatikiza apo, kuthekera kopanga mawonekedwe ovuta ndi magawo akulu kumatsegula njira zatsopano zopangira silicon carbide ceramic application. Mafakitale omwe amafunikira mapangidwe ovuta komanso zida zogwira ntchito kwambiri amatha kupindula ndi njira yokonzekera yatsopanoyi. Kusinthasintha kwa mapangidwe ndi kuthekera kopanga zinthu zambiri zama ceramics apamwamba kwambiri a silicon carbide kungapangitse kupita patsogolo kwakukulu m'malo monga zakuthambo ndi zamagetsi komwe magwiridwe antchito ndi ofunika kwambiri.
