Abstract ZrB2 was synthesized by heating a mixture of ZrO2, B2O3, and Na in a molar ratio of 1:1:5 at 873–1273 K. While unreacted ZrO2 remained in the sample synthesized at 873 K, single phase ZrB2 powders were obtained at temperatures ≥1073 K. The diameters of the ZrB2 particles obtained at 1073 and 1273 K were 0.1–20 and 10–100 μm, respectively. Single phase ZrB2 was also obtained at 873 K when the starting material was rich in B2O3 and Na (ZrO2:B2O3:Na = 1:5:15). This route yielded fine particle aggregates of ZrB2, which were found to be <0.1 μm in size.

使用 Na 由氧化物低温合成 ZrB 2 粉末

摘要 ZrB2 是通过将摩尔比为 1:1:5 的 ZrO2、B2O3 和 Na 的混合物在 873–1273 K 下加热合成的。虽然未反应的 ZrO2 留在在 873 K 合成的样品中，但在 873 K 下获得单相 ZrB2 粉末。温度≥1073 K。在1073 和1273 K 获得的ZrB2 颗粒的直径分别为0.1-20 和10-100 μm。当起始材料富含 B2O3 和 Na (ZrO2:B2O3:Na = 1:5:15) 时，也在 873 K 下获得单相 ZrB2。该途径产生了 ZrB2 的细颗粒聚集体，发现其尺寸 <0.1 μm。
