Chemistry of soil minerals. Part VII. Synthesis, properties, and crystal structures of salt-filled cancrinites Cancrinite has been synthesized in the sodalite crystallization field at 80° by addition of sodium nitrate, chromate, or molybdate. The crystals then cont... RM Barrer,JF Cole,H Villige...
Simple crystal structures are usually named after the compounds in which they were first discovered (diamond or zinc sulfide, cesium chloride, sodium chloride, and calcium fluoride). Many compounds of the types A+X-and A2+X2-have such structures. They are highly symmetrical, the unit cell is...

Crystals and minerals offer so many different uses in our world and are a part of our everyday needs in a variety of ways. Our food, medicine, structures, objects and healing tools are often made from various minerals. When it comes to crystals and minerals, many of us may not know exa...
Single crystals of the sapphirine and surinamite analogues in the MgO - Ga2O 3 - GeO 2 system have been grown from potassium molybdate fluxes. Their crystal structures and cation distributions have been determined by X-ray diffraction. Sapphirine, Mg (sub 8.9) Ga (sub 14.2) Ge (sub 4.9)...
