Abstract
For the development of sintered and recrystallized alumina, zirconia
or magnesia ceramics temperatures used are of the order of 1800°C.
Use of electrical furnaces is not convenient from economical as well
as fuel element point of view. Hence an attempt has been made to
develop a facility for high temperature gas fired furnace where
temperatures of the order of 1800°-1850°C can be obtained and
maintained for long periods.
In this paper, stepwise improvements in design for liquid petroleum
gas as fuel with air and oxygen gas mixture as well as the burner
port design have been described.
A suitable design with proper hot face of refractories like dense
alumina and zirconia bricks having a hot chamber of the size of
20 em x 10 em x 10 em, has been evolved and is being used regularly
for laboratory experiments on sintering of high temperature
oxide ceramics.
