| | BARIUM CARBIDE Usage And Synthesis |
| Description | BaC2 has the molecular
weight of 161.348 g/mol and the CAS number of 50813-
65-5. It is a gray cubic to rhombohedral crystal with
a density of 3.74 g/cc. | | Chemical Properties | gray tetr; -8 mesh 99.5% purity [CER91] [CRC10] | | Synthesis | According to 12% graphite powder (weight percentage), 80% barium oxide powder (weight percentage), 8% semi-solid binder (weight percentage), after 2 hours of mixing, in the steel mold two-way pressing forming into a billet, billet forming pressure of 60MPa; billet after 1250 ??, 5 hours of reaction synthesis of the vacuum furnace to become a billet containing a large number of pores; billet mechanically crushed ingots screened and purified, washed clean with alcohol and dried, to obtain a larger barium dicarbonate (BaC2) particles, the collected barium dicarbonate (BaC2) particles and the appropriate amount of barium dicarbonate (BaC2) particles, with Alcohol washed clean and dried to get a larger barium bicarbonate (BaC2) particles, the collection of barium bicarbonate (BaC2) particles and the appropriate amount of surfactant into the planetary high-energy ball mill, corundum ball mill tanks in the protection of argon gas, rotational speed of 800rad/min, ball milling time of 10 hours, will be collected in the fine BaC2 powder and a certain amount of solid binder in the steel mold in the two-way pressing , pressing molding pressure of 350 MPa, and further pressing with cold isostatic pressure equipment, pressing molding pressure of 300 MPa, the sample into the sintering furnace sintering, sintering temperature 1500 ??, sintering time of 4 hours, take out to get the grain size distribution uniformity, impurities less barium dicarbonide dielectric block material. |
