Description
This paper discusses the results of chemical studies cdrried out in
some clay deposits in three states of Nigeria. The clay samples were
obtained from Ngala, Shuwari and Pulka representing Borno State,
Ememukohwarien and Ubulu-Uku, Delta State and Jjetu in Edo
State. The results showed that alumina, silica and Lost-on-ignition
(LOI) values for shuwari are 36%, 47% and 8.5% respectively;
Pulka, -11.3%, 51.0%and4.01%; Ngala; 38.0%, 46.8%and 11.63%;
Ubulu-Uku, 40. 0%, 39.0% and 12. 0%, Eruemukohwarien, 29. 0%,
45.8% and 1-1. 7%; ljeiu, 41.5%, -15.8% and 10.2% respectively.
These results placed the Shuwari clay in the group of siliceous fireclay
refractory; Pulka clay, medium duty, low-melting semi-acid
fire-clay,· Ngala, low-duty and low melting fire-clay refractory;
Ubulu- Uku, under the super-duty, general purpose neutral fire-clay
refractory; Ememukohwarien, medium duty clay and ljetu, was
placed in the range of high refractory normal fire-clay group. The
possible areas of applicazions of all the investigated clays have also
been suggested in this paper
