黑锰矿

黑锰矿的PZC较高，表面可变负电荷量远低于其他3种矿物。

The PZC of the synthesized hausmannite is much higher than PZCs of other minerals , and it has the least surface variable negative charge .

通过偏光显微镜和反光显微镜观察试样釉层的显微结构，发现虹彩釉在成釉过程中釉层表面析出了针状的黑锰矿晶体。

The microstructure of the sample glaze layer under polarizing microscope and reflecting microscope has showed acicular hausmannite crystals on the glaze layer surface of luster glaze .

硬锰矿一种黑色氧化锰矿的混合物一种锰的氧化物，作为黑锰矿天然存在。

用氧化还原平衡法研究了水钠锰矿、钙锰矿和黑锰矿等三种不同结构类型氧化锰矿物对As（Ⅲ）的氧化特性，以及针铁矿对上述氧化的影响。

Oxidation characteristics of As (ⅲ) by three types of manganese oxide minerals and effects of presence of goethite were investigated by equilibrium technique of redox reaction .

结果得出，初始锰矿物是黑锰矿；控制锰矿物形成的条件是，除必要的物质来源外，起决定作用的是形成环境的酸碱度和氧化还原电位。

Experimental results show that primary manganese mineral is hausmannite and controlling conditions of manganese mineral formation are , besides essential material source , pH and Eh in the formation environment .

最后，通过化学浴沉积制备出黑锰矿四氧化三锰薄膜，并且研究了不同实验条件对薄膜影响。

At last , the Hausmannite manganomanganic oxide ( Mn3O4 ) thin films were deposited by chemical bath deposition and the affect of different deposition parameters on the films was also discussed .
