Final answer:
The structural portion of a ceramic article or the clay material from which it is made is called the ceramic matrix or ceramic composition. Ceramics are solid materials composed of inorganic compounds, such as metal or non-metal elements, and are bonded by ionic and covalent bonds. The most common ceramics include earthenware, porcelain, and brick.
Step-by-step explanation:
The structural portion of a ceramic article or the clay material from which it is made is called the ceramic matrix or ceramic composition. Ceramics are solid materials composed of inorganic compounds, such as metal or non-metal elements, and are bonded by ionic and covalent bonds. The most common ceramics include earthenware, porcelain, and brick. These materials are formed using clay or a mixture of clay and other substances, and they undergo firing at high temperatures to achieve their final structure.
