Anatase ke mofuta oa liminerale tse nang le methapo e itseng ea titanium. Liminerale ka mefuta ea tlholeho li kopana hangata joalo ka lesela le letšo, leha thepa e hloekileng e se na 'mala kapa e tšoeu. Mefuta e meng e 'meli ea tlhaho ea liminerale tsa TiO2 e tsejoa, e leng brookite ebile e le lesupi.

Anatase e lula e fumanoa e le likristale tse nyane, tse arohaneng le tse tsoetseng pele haholo, 'me joalo ka lesupi le tsitsitseng la thermodynamically, e lla ka har'a tsamaiso ea tetragonal. Lejoe la bohlokoa le khonahala ka linako tsohle tsa mocheso le likhatellong, ha polymorph e sentse e le litšila. Leha ho le joalo, anatase hangata ke karolo ea pele ea titanium dioxide ho etsa lintho tse ngata, ka lebaka la matla a tlase a lefats'e, ka phetoho ea ho senyeha ho etsahala maemong a phahameng a mocheso. Le ha tekanyo ea mohono o tšoana ka methati ka bobeli ea li-anatase le tse senyehileng, ha ho kamano pakeng tsa li-angle tse arohaneng tsa liminerale tsena tse peli, ntle le sebakeng sa prism-45 ° le 90 °. Pyramid e tloaelehileng ea anatase, e tšoanang le lifahleho tsa eona tse nang le masoba a phethahetseng, e na le sekhutlo ho feta mocheso oa 82 ° 9 ′, sekhutlo se lumellanang e le rutile e le 56 ° 52½ '.

Mekhoa e 'meli ea ho hola ea likristale tsa anatase e ka khetholoha. Ho atileng haholo ho etsahala joalo ka liphiramide tse bobebe tse bobebe tse peli tse nang le indigo-putsoa ho 'mala o moputsoa le pherese e tala. Likristale tsa mofuta ona li ngata ho Le Bourg-d'Oisans ho Dauphiné, moo li amanang teng le rock-kristale, feldspar, 'me e se nang moeli linthong tse betliloeng ka granite le mica-schist. Likristale tse tšoanang, empa tsa boholo ba microscopic, li ajoa haholo mafikeng a thellang, joalo ka litheko tsa lehlabathe, matlapa, le litheko, moo li ka arohanang ka ho tlosa likarolo tse bobebe tsa lefika le nang le phofo. Sefofane sa anatase ke sebaka se tsitsitseng sa thermodynamically mme ka hona ke sona sebopeho se pepesitsoeng ka ho fetisisa sebopeho sa tlhaho le sa maiketsetso.

Likristale tsa mofuta oa bobeli li na le lifahleho tse ngata tsa pyramidal, 'me hangata li boreleli kapa ka linako tse ling li tloaetse ho fetoha,' mala ke o-sootho ho sootho. Likristale tse joalo li tšoana hantle le sebopeho sa xenotime ka mokhoa o shebahalang, hape, e ne e le ka nako e telele ho neng ho nahanoa hore ke ea mofuta ona, lebitso le khethehileng la bohlale le ntseng le sebelisoa ho bona. Li hlaha li khokahantsoe le mabota a li-artvice ka har'a 'mala oa lithaba tsa Alps, Binnenthal haufi le Brig sebakeng sa canton Valais, Switzerland, e le sebaka se tsebahalang. Li-pseudomorphs tse hlahang ka tlhaho tsa rutile ka mor'a anatase le tsona lia tsebahala.
