Disclosed are an electrolyte matrix, particularly for a molten carbonate fuel cell, comprising a matrix material which contains one or several lithium compounds, aluminum oxide, and a carbide, and a method for the production thereof. The inventive matrix material contains a combination of lithium carbonate, aluminum oxide, and titanium carbide. Said matrix material can be produced in a simple manner from inexpensive materials that are available at the required degree of fineness, has a high degree of solidity in both the green state and the sintered state, and has good storage properties in the green state.
