Tuam Tshoj Boron Nitride Ceramics

Boron nitride ceramic yog ib hom kev lag luam ceramic khoom ua los ntawm boron nitride ua raw khoom. Nws txais cov yam ntxwv ntawm boron nitride, qhia qhov zoo ntawm qhov kub thiab txias, tsis muaj adhesion, corrosion kuj, tshav kub dissipation thiab siab thermal conductivity. Vim nws muaj ntau yam zoo, dab tsi yog kev siv boron nitride ceramics?

Boron nitride ceramics tuaj yeem siv los tsim cov cuab yeej siv ceev ceev thiab laum cov khoom siv rau kev tshawb nrhiav geological thiab roj drilling vim tias lawv tsis ntub los ntawm molten aluminium thiab tuaj yeem tiv thaiv cov khoom saum npoo ntawm cov ntaub ntawv ncaj qha nrog molten aluminium, magnesium, zinc alloys thiab lawv cov slag. .

Tsis tas li ntawd, boron nitride ceramics muaj cov khoom siv zoo heev, yog li lawv tuaj yeem ua rau kub kub, insulating thiab txias Cheebtsam, nrog rau cov khoom siv tshwj xeeb electrolytic thiab cov ntaub ntawv tiv thaiv uas tuaj yeem siv rau qhov kub thiab txias.

Cov ntaub ntawv kub kub insulating feem ntau yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm qhov siab melting point, qhov nruab nrab ntawm qhov tawg tsis kam thiab tshuaj lom neeg sib raug zoo ntawm qhov kub thiab txias. Boron nitride ceramics tsuas muaj qhov siab melting point thiab muaj kev tiv thaiv zoo ntawm qhov kub thiab txias. Tshwj xeeb, hexagonal sheet boron nitride ceramics muaj qhov zoo ntawm kev sib txhuam coefficient ntawm qhov kub thiab txias thiab zoo sib xws thermal expansion coefficient rau tungsten, uas yuav dhau los ua qhov zoo tshaj plaws kub kub insulating khoom.
