  We present results of three SLD analyses: our final determination of the rate
of gluon splitting into b-bbar, an improved measurement of the inclusive b
quark fragmentation function in Z0 decays, and a preliminary first measurement
of the energy correlation between the two leading B hadrons in Z0 decays. Our
results are obtained using hadronic \z0decays produced in e+e- annihilations at
the Stanford Linear Collider (SLC) between 1996 and 1998 and collected in the
SLC Large Detector (SLD). In this period, we used an upgraded vertex detector
with wide acceptance and excellent impact parameter resolution, thus improving
considerably our tagging capability for low-energy B hadrons.
