Boron

Boron inoratidzwa patafura ye periodic ine chiratidzo B, atomic nhamba 5, uye atomic mass ye10.81. Elemental boron, ine semi-metallic uye semi-conductive zvivakwa, iri muboka 3A pane periodic tafura. Boron iripo mumasikirwo ari maviri isotopes - B10 uye B11. Kazhinji, borates inowanikwa mune zvakasikwa seB10, isotope 19.1-20.3% yenguva uye B11 isotope 79-80.9% yenguva.

Elemental boron, iyo isingawanikwe mumasikirwo, inoumba zvisungo zvakasiyana-siyana zvesimbi uye zvisiri-metallic zvinhu kuti ibudise makomisheni ane akasiyana zvimiro. Naizvozvo, maumbirwo eborate anogona kushandiswa mumaindasitiri mazhinji akasiyana zvichienderana neakasiyana anosunga makemikari. Kazhinji, boron compounds inoita senge isiri-metallic compounds, asi boron yakachena ine magetsi ekugadzirisa. Crystallized boron yakafanana nechitarisiko kune, ine optical properties senge, uye inenge yakaoma semadhaimani. Pure boron yakawanikwa kekutanga muna 1808 neFrench chemist JL Gay - Lussac naBaron LJ Thenard uye English chemist H. Davy.

Zvinangwa zvinogadzirwa nekubatanidzwa kweBoron powders kusvika kuzere density. Izvo zvakabatanidzwa zvinhu zvinosarudzwa kunyungudutswa uye zvino zvinogadzirwa kuita inodiwa chimiro chechinangwa.

Rich Special Equipment ndiye Mugadziri weSputtering Target uye anogona kuburitsa kuchena kwakanyanya kweBoron Sputtering Materials zvinoenderana neVatengi 'zvakatemwa. Kuti uwane mamwe mashoko, tapota taura nesu.
