| 摘要 |
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.
