These are 1 friable soil with high content of secondary concretions of sesquioxide clays. NO is called "nitrogen sesquioxide" ("sesqui-" means ). The lattice parameters for three of the polymorphic structures of curium sesquioxide are given below. C produces the sesquioxide (CfO). Samarium (and its sesquioxide) are paramagnetic at room temperature. The most stable oxide of samarium is the sesquioxide SmO. It takes hundreds of thousands of years of leaching to create sesquioxide clays. Curium sesquioxide can be prepared in a variety of ways. Amorphous and sesquioxide clays have the highest AEC, followed by the iron oxides. The mineral contains 89.7% manganese sesquioxide; it dissolves in hydrochloric acid with evolution of chlorine. Curium sesquioxide will spontaneously react with gaseous oxygen at high temperatures. For example, aluminium oxide () is a sesquioxide. A further sesquioxide, PbO, can be obtained at high pressure, along with several non-stoichiometric phases. Aerosolized Curium Sesquioxide&colon; The aerosolization process of CmO can be done through multiple experimental processes. A sesquioxide is an oxide with three atoms of oxygen and two metal atoms.
