The authors study reduction of longitudinal ultrasonic oscillations (internal friction Q-1 and logarithmic decrement δ) in NaClO3 crystals within the temperature range of 78 - 525 K and relative amplitudes of oscillatory deformation of 10-7 - 10-5 according to the method of compound piezoelectric vibrator at the frequencies of ≈ 105 Hz. Q-1 maximums under the temperatures of 110 K, 240 K, 260 K, ≈ 400 K and its fast growth under the temperature over 500 K are revealed as well as athermic peak of 8 in the region of small deformation amplitudes (near 10-7).
