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 th<! investigated clays have also been suggested in this paper
