A METHOD FOR THE PREPARATION OF AN ALKALINE METAL CHLORATE BY ELECTROLYSIS OF A SOLUTION OF A CHLORIDE OF SAID METAL COMPRISING THE STEPS OF CIRCULATING SAID CHLORIDE SOLUTION IN AN INTERELECTRODE SPACE BETWEEN A CATHODE AND AN ANODE, ESTABLISHING BETWEEN SAID CATHODE AND SAID ANODE A CURRENT DENSITY SUFFICIENT TO FORM CHLORINE NEAR THE ANODE AND TO CAUSE OH-IONS WHICH ARE FORMED AT THE CATHODE TO MIGRATE TOWARDS THE ANODE, THE CIRCULATING SPEED AND THE CURRENT DENSITY BEING SELECTED, AS FUNCTIONS OF EACH OTHER, SUCH THAT THE SPEED IS SUFFICIENTLY HIGH AND THE CURRENT DENSITY SUFFICIENTLY LOW, SO THAT SAID OHIONS FORMED NEAR THE CATHODE CANNOT, ON THE AVERAGE,
