Calcium hexaboride Calcium boride CaB6 hmoov

1, CAB₆yog dub thiab grey hmoov. Lub melting point yog 2230 ° C.Ntawm qhov mob ntawm 2.33gs / cm2³thiab qhov kub ib txwm ntawm 15 ° C nws tsis tuaj yeem fused hauv dej.

2, Silicon Boride yog dub thiab grey hmoov nrog luster. Qhov txheeb ze ntom ntom yog 3.0g / cm3³. Lub melting point yog 2200 ° C; Lub abrading thiab txiav efficiency siab dua silicon carbide. Nws tsis yaj nyob rau hauv dej thiab anti-oxidant, tiv thaiv tshav kub concussion, anti-causticity. Nws muaj siab intension thiab stability.

3, Feem ntau siv particle loj: 20 ~ 100mesh; 20 ~ 60mesh; - 20mesh

Siv cov khoom siv

CaB₆

1, Antioxidant, anti-eroded thiab refractory nrog boraciferous additive, uas yog siv rau dolomite carbon thiab magnesia dolomite carbon cov ntaub ntawv.

2, Cov khoom siv tshiab siv rau kev lag luam nuclear rau neutron-tiv thaiv thiab high-purity hlau borid (TiB₂, ZIB₂, HfB₂thiab lwm yam) thiab high-purity boron alloy (Ni-B, Co-B, Cu-b thiab lwm yam).

3 ,cav₃B₂N₄thiab hexa nitride sib tov siv los ua activator Ca₃B₂N₄. Nws tuaj yeem tsim cov khoom siv lead ua zoo B₂N₄.

4, Siv rau oxygenate rau High Conductivity nyob rau hauv tooj liab zog.

5, Cov khoom siv semi-conductor tshiab rau qhov kub thiab txias 900 K nrog automat hluav taws xob module.

6, Siv rau desulfurize, deoxidize thiab nce boron rau boron alloy.

7, Siv los ua peb chlorination (BCL₃s) thiab unformed boride.

tooj liab deoxidizer:

1. Alcium hexaboride: Qhov zoo tshaj plaws oxygen deoxidizer uas siv rau cov tooj liab dawb, Cov txiaj ntsig tau pom tias deoxidizing muaj peev xwm ntawm calcium hexaboride deoxidizer yog siab dua li ntawm tooj liab boron alloy thiab phosphor tooj liab. thiab nws muaj kev txhim kho cov nyhuv ntawm tooj liab matrix thiab tsis muaj kuab paug rau tooj liab kua. Ntxiv cov Alcium hexaboride> 0.60% tuaj yeem txo cov pa oxygen ntawm cov kua tooj liab mus rau <20 × 10- 6, Uas tuaj yeem ncav cuag tus qauv hauv tsev ntawm qib thawj qib oxygen-dawb tooj liab.
2. Calcium hexaboride muaj kev cuam tshuam me ntsis ntawm cov hluav taws xob conductivity ntawm tooj liab. Ntxiv ntau yam ntawm Alcium hexaboride (0.69% ~ 1.12%).
3. Nrog rau qhov nce ntawm calcium hexaboride, lub zog tensile ntawm tooj liab yuav txuas ntxiv txhim kho, thaum cov nyiaj ntxiv ntawm calcium hexaboride ncav cuag 0.88% mus txog qhov siab tshaj plaws.
