Abstract
An electrically conductive titanate derivative containing an element other than titanium is prepared by baking a mixture of a titanate and a compound containing an element other than titanium.
Claims7
An electrically conductive titanate of the formula:
- M.sub.x O.n(Ti.sub.1-z L.sub.z O.sub.2-p)
- wherein M is alkali metal, n is an integer of 1 to 10, x is 1 or 2, L is at least one element of group (V) of the periodic table other than nitrogen, p is a number of 0.ltoreq.p<2, and z is a number of 0<z.ltoreq.1/2, said element being introduced in an amount of 0.01 to 50 mole% based on one atom of titanium.
A process for preparing an electrically conductive titanate derivative of the formula:
- M.sub.x On(Ti.sub.1-z L.sub.z O.sub.2-p)
- wherein M is alkali metal, n is an integer of 1 to 10, x is 1 or 2, L is at least one element of group (V) of the periodic table other than nitrogen, p is a number of 0.ltoreq.p<2, and z is a number of 0<z.ltoreq.1/2, said element being introduced in an amount of 0.01 to 50 mole% based on one atom of titanium, said process comprising baking a mixture of a titanate and a compound containing said at least one element, said mixture containing 0.001 to 100 parts by weight of said compound per 100 parts by weight of said titanate, said baking being conducted at a baking temperature of 600 to 1500 degrees centigrade.
