Clay Based Ceramics Sintering

After the pottery has sintered it is no longer truly clay but has become a ceramic material.

Clay based ceramics sintering.

While commonly related to powder processing of ceramic parts its important roles in other processes such as additive manufacturing nanotechnology and thin films are less commonly discussed. Clay based porous ceramic was prepared from clay banana peel mixtures. Beginning at about 1650 f 900 c the clay particles begin to fuse. From table 3 and figures 2 and 5 the effects of sintering temperature on the apparent porosity and water absorption of the sintered clay based ceramic is vividly shown.

A treatment in which a green body is converted to a stronger monolith while ceramic artifacts found in archaeological sites indicate sintering practice even in the upper paleolithic era i e. The anorthoclase and mullite phases increased as sintering temperature was increased. Apparent porosity and water absorption. The term sintering basically defines a process of bonding densification and or recrystallization of powder compacts i e.

Sintering is a ubiquitous processing step for manufacturing ceramics for a diverse set of applications. Sintering of clay powders is recommended to be carried out above 900 c to benefit from fluxing phase consolidation. Higher sintering temperature 1100 c had a positive influence on tensile strength. The influence of sintering temperature was evaluated.

This cementing process is called sintering. Specifically gravettian around 26 000 years ago. However solid state consolidation of clay bodies made with mixture of powders may occur bellow this temperature by surface diffusion within the nanopores of the layered. The driving force of sintering process is reduction of surface energy of the particles.

Clay based ceramic is one of the most used materials in the form of construction blocks bricks and tiles. Effects of sintering temperature on the mechanical properties of the clay based ceramics.
