A vacuum insulating glass (IG) unit. In certain embodiments, single crystal spacers (e.g., of aluminum oxide) are provided between opposing substrates so as to maintain a low pressure space therebetween. The single crystal nature of the spacers enables them to be small enough so that they are not visibly obtrusive, and yet strong enough to maintain the low pressure space. In certain embodiments, the spacers may be of a hexagonal platelet shape.

1. A thermally insulating glass panel comprising:first and second spaced apart glass substrates defining a low pressure space therebetween having a pressure less than atmospheric pressure; a plurality of spacers disposed between said first and second glass substrates for spacing said substrates from one another in order to maintain said low pressure space therebetween; and wherein at least one of said spacers is a single crystal structure having a maximum thickness of from about 10 to 100 .mu.m.
