- Rice husk contains
about 80 % organic matter such as cellulose, lignin etc. and rest
mineral components such as silica, alkalis and trace elements
-
The fabrication of the
refractory was done from several different formulations containing Rice
Husk Ash, Starch and Bentonite as binders and plasticizers; wood saw
dust, flux and water.
-
Products made using rice
husk develop plenty of pores during heat treatment due to burning out of
organic material. The more the percentage of rice husk in a product, the
more porous would be the product and better thermal insulation.
Presences of entrapped air in pores have thermal insulating
characteristics and thus make the porous fire product structure suitable
for back up insulation.

Rice Husk Ash is used
during the production of high quality flat steel. The ash also finds
application as an excellent insulator, having fine insulating properties
including low thermal conductivity, a high melting point, low bulk
density and high porosity. It is used as "tundish powder" to insulate
the tundish container, prevent rapid cooling of steel and ensure uniform
solidification in casting process. RHA is also used as a coating over
the molten metal in the tundish and in ladle which acts as a very good
insulator and does not allow quick cooling of metal
