What Bob said for me too.  I always use anti sieze (on threads only) and had no problem.  Of course there is the possibility that you had a gob of it fly off the EGT mount and land smack dab on the O2 sensor.  That might do it harm.

Hi Bill,

I'm pretty sure I used the copper anti-seize compound on my O2 sensor.
I lost two of them in the first two hours of flight because the wire
broke off.  It was unsupported for several inches and I think it was
vibrating.  I don't think the anti-seize will hurt anything as long as
you don't get it on the sensor itself.
