The investigations on the usage of the alternative
raw materials have been always popular in the ceramic industry. Manufacturers
have been interested in this subject for both increasing product quality and
decreasing production costs.
The aim of this study is to provide the recycling of
rice husk, which is the waste material of rice, produced abundantly in the
world and in our country. Thus, it is aimed to prevent the environment and
stock area problems. With this purpose, studies have been carried out to use
rice husk ash in the production of ceramic coating material. Rice husk ash is
obtained by applying heat treatment to the rice husk. The ash obtained under
suitable combustion conditions contains a high amount of silica and the ash has
a high specific surface area value. Quartz is used as a source of silica in
ceramic coating materials. In this study, the use of rice husk ash instead of
quartz was studied in ceramic coating materials due to its high silica content.
The aim of this study is to investigate the
usability of rice husk ash in the production of ceramic coating material. In
this context, rice husk ash samples were characterized by XRD, SEM and chemical
analyses. Utilization of rice husk ash in raw glaze compositions have been
carried out. Color changes of the fired glazes were observed by color measuring
device. Sodium borosilicate glass production studies were carried out by using
rice husk. The samples were fused at 1000°C and 1100°C. The metal surface coating studies were carried
out by using sodium borosilicates obtained from rice husk ash. The obtained
glasses were ground, mixed with water and applied on 304 stainless steel
plates. The samples were fired at 900°C and 950°C as two separate groups. It
was observed that glassy structures were developed on the metal surfaces.
As a
result of these studies, it has been observed that rice husk ash is an
alternative raw material that can be used instead of quartz in the production
of ceramic coating material.
