Novel dense crystal structure of high-pressure synthetic K8Ca3(CO3)7 as described through cation-carbon nets
{{output}}
K8Ca3(CO3)7 was synthesized at 1200°C and 6 GPa. Its layered triclinic crystal structure presents a new type characteristic of high-pressure K-Ca carbonates. It is also the second example of K/Ca disorder coupled with orientational disorder of carbonate anion... ...
