Silicon hlau ua Hoobkas muab 553 3303 silicon hlau

1. Kev kub siab ua haujlwm, txawm tias tom qab ultra-siab kub arc hlawv, qhov poob qis me me, thiab thermal expansion coefficient kuj me me.Lub zog ntawm hlau silicon nce nrog qhov kub thiab txias, thiab ntawm 2000 ° C, lub zog ntawm hlau silicon ob npaug.

2. Hluav taws xob thiab thermal conductivity, qhov conductivity ntawm hlau silicon yog 100 npaug siab dua li ntawm cov ntxhia uas tsis yog xim hlau.Thermal conductivity tshaj cov khoom hlau xws li hlau, hlau, thiab txhuas.Lub thermal conductivity txo qis nrog qhov nce ntawm qhov kub thiab txias, thiab txawm tias nyob rau hauv qhov kub thiab txias, hlau silicon ua ib lub tshav kub insulator.Hlau silicon tuaj yeem ua hluav taws xob vim tias txhua cov pa roj carbon atom hauv hlau silicon tsuas yog tsim 3 covalent bonds nrog lwm cov pa roj carbon atoms, thiab txhua cov pa roj carbon atom tseem khaws 1 cov hluav taws xob dawb los thauj cov nqi.

3. Lubricity.Lub lubricating kev ua tau zoo ntawm hlau silicon nyob ntawm qhov loj ntawm cov hlau silicon nplai.Qhov loj ntawm cov nplai, qhov me me ntawm kev sib txhuam coefficient thiab qhov zoo ntawm lubricating kev ua tau zoo.

4. Tshuaj stability.Hlau silicon muaj cov tshuaj lom neeg ruaj khov ntawm chav tsev kub, thiab tuaj yeem tiv taus cov kua qaub, alkali thiab cov kuab tshuaj organic.

5. Plasticity, hlau silicon muaj zoo toughness thiab tuaj yeem dov rau hauv cov ntawv nyias nyias.

6. Thermal shock resistance.Thaum siv nyob rau hauv chav tsev kub, hlau silicon tuaj yeem tiv taus qhov kub thiab txias tsis muaj kev puas tsuaj.Thaum qhov kub thiab txias hloov pauv, qhov ntim ntawm cov hlau silicon tsis hloov ntau, thiab tsis muaj qhov tawg yuav tshwm sim.
