We present ultrasonic velocity and attenuation measurements of the Sb-substituted compounds Yb4(As1-xSbx)3, x = 0, 0.12, 0.24, 0.29. The results of our experiments reveal that the one-dimensional charge ordering of Yb3+ along [1 1 1] direction in Yb4As3 changes into a charge glass order in Yb4(As0.71Sb0.29)3.
