The furnace increases in temperature from a first temperature to a second temperature during firing, and the green body sinters at the second temperature to form a sintered lithium garnet. The green body shrinks 35% or less along one dimension after firing to form the sintered lithium garnet.
Methods of manufacturing a ribbon include contacting the ribbon with a recess of a forming roll to impart a protrusion to a first major surface of the ribbon.
