Tiv Tauj Peb

Kev ua lag luam ua rau muaj kev ua kom pom zoo rau cov neeg muaj txiaj ntsig zoo nrog cov khoom siv zoo tshaj qhov ntsuas kub thiab zoo heev rau ntau txoj kev corrosives, hauv cov hydroxides.

A335 P9 cov yeeb nkab yeeb siv hlau tseem muaj Manganese, sidlicon, carbon thiab phosphorus nyob rau hauv nws muaj pes tsawg leeg. Qhov sib ntxiv ntawm cov ntaub ntawv ua rau cov khoom muaj zog dua nrog cov txiaj ntsig siab dua thiab lub zog tensile. Vim yog cov ntsiab lus chromium siab, cov nyhuv redox yog siab.
