Yuav ua li cas ntxuav lub alumina crucible?

Alumina crucible, square alumina crucible, alumina corundum ark (rectangular alumina ceramic crucible), ncaj (cylindrical) alumina crucible thiab ntau yam tshwj xeeb zoo li alumina ceramic crucibles. Nws yog tsim rau ntau lub chaw soj nstuam, chaw soj nstuam, cov qauv hlau thiab cov hlau tsis yog hlau thiab cov ntaub ntawv melting thiab ntau yam kev lag luam tsom.

Yuav ua li cas ntxuav nws?

1. Acid ua npuas ncauj: feem ntau yog tsau rau hauv nitric acid ntev; ces ntxuav nrog dej

2. Qhuav, maj mam kub txog 800 ℃ hauv 6 teev nyob rau hauv lub qhov cub kub kub

3. Tshem tawm tom qab txias thiab npaj siv.

Ntxiv nrog rau impurities, cov teeb meem insoluble hloov dua siab tshiab rau hauv soluble nitrate kom tshem tawm

Tshem tawm cov kab ntawm nitrate hauv lub crucible (thermal decomposition method): xyuam xim rau cov cua kub yuav tsum tsis txhob ceev, txwv tsis pub lub crucible yuav tev (tawg puas).
