Perovskite's unit cell structure is cubic with titanium atoms at the corners, oxygen atoms at the midpoints of the edges with a calcium atom in the center. Its ABX3 cubic crystal structure corresponds to A (Calcium) which is a large, positively charged cation at the centre; B (Titanium), also cations, at the corners with smaller atom X (Oxygen), a negatively charge anion occupying the faces of the cube.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years and are compatible with every molecular model kit we have sold. This level of quality may appear expensive but no parts support from other vendors costs even more.
