Key Njirimara

Iron oxide - silver metal bụ nnọọ ductile. Ọ lends onwe ya nke ọma ọtụtụ ụdị nke machining: ibe ya bụrụ, Rolling. Ike igbari ọtụtụ ọcha ọtụtụ-eji na mmepụta nke ọtụtụ alloys. Active chemical mmewere interacts na fọrọ nke nta niile itughari asịd na-etolite a compound kwekọrọ ekwekọ valence. Ma, ọ na-akpa àgwà dị nnọọ nanị na lekwasị asịd. Pure ígwè na-akwadebe site na teknuzu nhazi nke minerals, nke bụ ugbu a na -nnoo ihe oxide ígwè.

Iron ogige etolite ahịrị abụọ: compound 2-valent na 3-valent. Onye ọ bụla n'ime ha e ji ya oxide. Kpụrụ ígwè compound site na mgbasa na asịd. ígwè salts hydrolyze 3 ike, ya mere nwere a odo-agba aja aja na agba, ọ bụ ezie na mmewere bụ colorless. Iron ogige na-ọtụtụ-eji nkà mmụta banyere ígwè ka a na mbenata gị n'ụlọnga, na akụ na ụba mba na akara nke pests na akwa ụlọ ọrụ, wdg Anhydrous ígwè oxide 2 na-kwadebere si 3 site Mbelata oxide dị ka a nwa powder, ebe nkwadebe nke ígwè oxide 3 emee site calcining ígwè hydroxide 3. oxides underlie nweta ígwè salts. A ka nwere obere mara dị ka acid compound na compound na a valence nke +6. Mgbe gwakọtara oxide 3 kpụrụ ferrites na ferrates, ọhụrụ, ma nke ọma na-amụ compound.

Njupụta na ọdịdị

The kọwara mmewere na ya ogige na-ekesa na ọdịdị. N'ụdị red, limonite ígwè oxide 3 emee n'ụdị magnetite - Fe3O4. N'ihi na mmepụta nke na igirigi ibu sulphuric acid ígwè pyrites (sulphide) na-eji. Oxides bụ ebe bụ isi nke ígwè na ígwè. Steel na ígwè nwere ihe dị otu mejupụtara, naanị ihe dị iche bụ na carbon ọdịnaya. Iron alloys nwere ihe na-erughị 2,14% carbon, steels na-akpọ, na ndị ọzọ karịa 2,14% - ígwè. Nke a na-ekesa bụ adabara mgbagwoju steels dị ka alloy, n'ihi na ha nwere a ihe mgbagwoju Ọdịdị na-ji ọnụnọ nke ọzọ ọcha.
