Question

A ceramic is produced from a powder in three primary steps: 1. First the powder milled, which is when the particles are ground to a mostly uniform size particle size difference is too great. the structure of finished ceramic becomes weaker. 2. Then, the milled powder is mixed with water such that clay can be molded into a workable from (e.g., the shape of a cup) 3. The third primary step is sintering, where the heated to a high enough to temperature to allow for a network sold to form (i.e., new bonds are formed to create an extended network of atoms) but a low enough temperature to avoid liquefaction (loss of stiffness). The heated material during the sintering process is referred to as a melt. Once enough time has passed to form the network solid, the melt is cooled to yield the finished ceramic product. Slowly cooling the melt gives enough time for the atoms to organize into a highly ordered or crystalline network, which is common for most ceramics. Some ceramics can undergo verification to produce a different type of finished product, where the melt is rapidly cooked. Since the atoms are randomly ordered the melt, Verification produces a network sold where the atoms are randomly ordered because time is needed for the atoms organize into a repeated

Explanation / Answer

Silicate ceramics:
Amorphous glass phase with a porous structure
Main component: SiO2
Small quantities of: Al2O3, MgO, ZrO2

In the given list: ZrSiO4 (made by fusion of SiO2 and ZrO2) and (MgO)3(SiO2)4 are the silicate ceramics

Oxide Ceramics – Principally contains Al2O3, MgO, ZrO2 with either no glass phase or small content.

In our list - Zirconium Oxide (ZrO2) is the Oxide Ceramics.

Non-Oxide Ceramics: which does not have oxygen; SiSiC/SSiC/ Si3N4

In the given list; Si3N4 is the oxide ceramics
