- Pyrite and sphalerite were grounded to 0.147 mm in a cylinder mill and chalcopyrite and galena to 0.097 mm in an agate ball mill. The F-test results showed that the degree of homogeneity is satisfactory for all samples. 黄铁矿和闪锌矿用棒磨机少量多级粉碎至0.;147mm，方铅矿和黄铜矿用小型玛瑙球磨机粉碎至0
- The results show that the conformation of mixture has a significant difference for these two sorts of ball. The homogenous fine mixed powder will be obtained for agate ball, whereas the conglomeration will be formed for steel ball. 结果表明,在其它实验参数相同的情况下,用两种不同材质的磨球所获得的混合粉形态有很大差异,用玛瑙磨球可以更好地使Ti2SiC2颗粒细化并均匀分散在Cu基体中,而用钢球则易产生混合粉的团聚。
- Steel ball and agate ball were selected during the ball-milling process and the effect of different balls on homogeneous distributing of micro-sized Ti 2 SiC 2 particle in Cu matrix was investigated. 分别选用钢球和玛瑙球进行球磨,对Ti2SiC2颗粒的细化和在Cu中分散性的影响进行了研究。
- Steel ball,agate ball and zirconia ball were selected during the ball-milling process and the effect of different balls on dispersity of nano-sized SiC particle in Al matrix was investigated. 研究了球磨过程中选用钢球、玛瑙球和氧化锆三种不同材质的磨球对SiC纳米颗粒在Al中分散性的影响。
- The particle size of Ti_3SiC_2 will be decreased to about 100 nm and the particles distribute homogeneously in the aluminum powder prepared with zirconia balls,whereas the conglomeration will be formed using steel balls and agate balls. 采用氧化锆磨球可以使Ti3SiC2的颗粒更好地细化且均匀分散在Al基体中,而用钢球和玛瑙球则易产生混合粉的团聚。
