APA TEGESÉ ALLOPHANE ING BASA INGGRIS?
Allophane
Allophane minangka amorf kanggo kristal mineraloid silikat aluminium silikat hidrolik. Rumus kimia iku Al2O3 · 1.3-2 · H2O. Amarga wis urutan atom sing cendhak, iku mineraloid, tinimbang mineral, lan bisa ditemokake kanthi spektrum infra merah sing khas lan pola difraksi sinar X. Bab iki pisanan diterangake ing 1816 ing Gräfenthal, Thuringia, Jerman. Allophane minangka produk alterasi cuaca utawa hidroterma gelas vulkanik lan feldspars lan kadhangkala nduweni komposisi sing mirip kaolinit nanging umume nduweni rasio molar Al: Si = 2. Biasane, bentuke ing ngisor asam lemah ing pH netral. Strukturé wis diajokaké, nanging padha karo mineral lempung lan dumadi saka lapisan octahedral aluminium lan lapisan tetrahedral silika. Transmisi elektron mikroskop nuduhake yen umume digawe saka aggregates spherules rongga ~ 3-5 nm. Allophane bisa ngowahi kanggo mbentuk halloysite ing resilicating kondisi banyu lan bisa ngowahi kanggo mbentuk gibbsite ing kondisi desilicating. A tembaga sing ngandhut macem-macem cupro-allophane wis kacarita.
Definisi saka allophane ing bausastra Basa Inggris
Définisi allophane ing kamus iku mineral amorf sing diwarnai kanthi warna sing kasusun saka silikat aluminium sing berair, lan dumadi ing retakan ing sawetara batu sedin.

The most important type of clay in this group is perhaps allophane. It is found
especially in volcanic ash soils. The name allophane was first introduced by
Stromeyer and Hausmann in 1861 for hydrous aluminosilicates occurring in
nature.

The high phosphate retention (307-402 mmole P per 100 g clay) and very low
ratio of CEC to phosphate retention (0065-0186) were considered to characterize
allophane. Wada (1959) studied the reaction of 1 M ammonium phosphate with ...
