Classify each of the following as a component of a silicate ceramic, an oxide ceramic, or a nonoxide ceramic. c. MoSi₂

Video transcript

Hey everyone in this example, we're told that ceramics can be classified into three categories oxide ceramics, non oxide ceramics and silicate ceramics. We need to classify zirconium, silicon tetroxide as one of the three classes. So what we should recognize first is that zirconium Is atomic number 40 on our periodic table and is located in the transition metal section and as an ion, it would form the ZR four plus charge. Now, as far as the rest of the bonds in the molecule, we have S. I. 04, which we should recognize as a poly atomic ion, which would be our silicate ion. Recall that silicate as an ion is S I minus. And because our formula is E R S I 04, we can see that our charges were exchanged here. So we had a transfer of electrons to give us a neutral compound. But more importantly because we have the presence of silicate here, we can say that therefore this compound is going to be silicate ceramic. And so silicate ceramic would be our final answer to complete this example. So I hope that everything I explained was clear. If you have any questions, please leave them down below and I will see everyone in the next practice video
