Hlau nplaum

Lub magnetism ntawm hluavtaws pob zeb diamond hmoov yog txiav txim los ntawm nws sab hauv impurity. Qhov tsawg dua qhov impurity muaj, qhov qis dua cov hlau nplaum, qhov siab dua toughness, qhov zoo dua particle zoo thiab thermal stability.

Txoj kev kuaj: Muab cov abrasives rau hauv lub thawv kuaj, qhov screen ntawm lub tshuab kuaj yuav qhia tus nqi magnetism.
