Zirconia Sib Tsoo Media

Vim tias yttria-stabilized zirconia hlaws muaj qhov ceev ntawm kwv yees li 6.0 g / cm³ - ntau dua ob npaug ntawm cov iav hlaws (2.5) thiab 60% siab dua alumina (3.6-3.9) - txhua qhov kev sib tsoo hloov mus deb dua lub zog kinetic rau lub hom phiaj hais. Nyob rau hauv high-speed stirred zeb, qhov no txhais tau hais tias tib lub sij hawm sib tsoo tsim cov khoom finer, los yog tib fineness tiav nyob rau hauv tsawg lub sij hawm. Rau lub lithium roj teeb cathode chaw tsim tshuaj paus tsim 10 tons ntawm LFP ib hnub twg, txo kev sib tsoo lub sij hawm los ntawm 30% txhais ncaj qha mus rau nce throughput thiab txo nqi zog ib kilogram.

Vim hais tias cov hlaws dai tsis muaj hlau dawb, tsis muaj cov hlau tsis muaj hlau, thiab tsis muaj cov hlau tsis huv, cov hlau tsis huv nkag mus rau hauv cov khoom ntws. Hauv kev tsim cov roj teeb lithium, txawm tias 10 ppm ntawm hlau los ntawm cov xov xwm steel tuaj yeem ua rau muaj kev cuam tshuam sab nraud uas txo lub peev xwm thiab lub neej voj voog. Hauv cov iav dawb ceramic, hlau ua rau tsis muaj xim - tig dawb glaze grey lossis xim av. Hauv kev ua tshuaj API, kev sib kis ntawm cov hlau ua txhaum txoj cai purity cov qauv. Zirconia hlaws tshem tawm tag nrho cov kev pheej hmoo no. Rau cov neeg lag luam wholesale, qhov no txhais tau tias koj cov neeg siv khoom hauv kev lag luam siab huv tsis muaj lwm txoj hauv kev - lawv yuav tsum siv zirconia, thiab lawv yuav them tus nqi.

Vim hais tias cov hlaws dai yog sintered kom tag nrho ntom nrog cov nplua-grained, pore-dawb microstructure, nws tus kheej hnav poob qis dua 0.01% ib 24 teev. Cov iav hlaws yuav poob 0.1-0.5% txhua hnub. Tshaj li ib xyoos ntawm kev ua haujlwm tas mus li, qhov sib txawv txhais tau hais tias zirconia hlaws yuav tsum tau siv qee lub sijhawm ntxiv, thaum iav hlaws yuav tsum tau hloov ntau zaus. Rau cov xim zeb ua haujlwm 8,000 teev hauv ib xyoos, hloov los ntawm iav mus rau zirconia hlaws tuaj yeem txo cov nqi siv xov xwm los ntawm 70-80% ib xyoos ib zaug, thaum tshem tawm cov kab mob sib kis.

Vim tias yttria stabilizes tetragonal siv lead ua theem, cov khoom ua tiav cov pob txha toughness tshaj 8 MPa·m¹/² - roughly 65% ​​siab dua alumina (4.6). Thaum tawg pib tsim, tetragonal nplej hloov mus rau monoclinic, nthuav me ntsis thiab muab cov kab nrib pleb rau hauv compression. Qhov no txwv qhov tawg ntawm propagating. Hauv ib lub tshuab hluav taws xob siab uas cov iav los yog cov hlaws txheem ceramic yuav tawg, zirconia hlaws nyob twj ywm. Tsis muaj cov hlaws tawg txhais tau hais tias tsis muaj cov kab mob kis tau rau cov khoom thiab tsis muaj cov pob zeb nres los ntawm cov khib nyiab clogging lub vijtsam tawm.
