Cov lus qhia ntxaws txog lub cev thiab tshuaj lom neeg ntawm tungsten crucibles
Cov Khoom Siv Lub Cev
Ntom ntom: lub ntom ntawmtungsten cruciblesyog tus tseem ceeb, feem ntau yog dua 18.5g / cm³, thiab qhov ntom ntawm forged tungsten crucosbles tuaj yeem ncav cuag 19.35g / cm³.
Melting point thiab boiling point: Lub melting point ntawm tungsten yog 3410 thiab boiling point yog 5700, uas ua rau tungsten crucibles tsis tshua muaj resistant rau kub kub.
Coefficient ntawm thermal expansion : Tungsten muaj qhov coefficient qis ntawm thermal expansion, uas txhais tau hais tias nws muaj qhov hloov me me thiab kev ruaj ntseg ntawm qhov kub thiab txias.
Hardness: tungsten crucibles muaj lub siab tawv thiab haum rau qee sij hawm uas yuav tsum tau hnav tsis kam.
Cov txheej txheem kev npaj nto: los ntawm kev npaj sib txawv, tungsten crucibles nrog qis npoo rougness tuaj yeem txhim kho lawv qhov zoo.
Cov khoom siv tshuaj
Corrosion Kuj: Tungsten crucailes tsis cuam tshuam nrog huab cua thiab dej ntawm chav tsev kub. Ntawm 80-100, tshwj tsis yog rau hydrofluoric acid, lwm cov kua qaub xws li cov kua qaub hydroc acid, thiab nitric acid muaj cov nyhuv tsis muaj zog ntawm tungsen crucibles. Oxidation resistance: At high temperatures, tungsten crucibles can combine with elements such as chlorine, bromine, iodine, carbon, and nitrogen, but not with hydrogen.
Kev kho cua sov: Cov txheej txheem kho cua sov ntawm tungsten crucibles tuaj yeem ua raws li kev tiv thaiv hydrogen los tiv thaiv oxidation.
