Figure 1(a) shows the three-dimensional model of the novel slotted helix SWS, which consists of a slotted helix tape, three Beryllia support rods and a stainless steel shell.
The plates are commonly made of alumina, but when large lateral heat transfer is required, higher thermal conductivity materials such as beryllia and aluminum nitride are desired.
Construction material consists of either an alumina or beryllia body with a proprietary resistor element for optimum performance.

Some data are presented in Appendix B of a 1/8 inch G-10 substrate and a thick disk of beryllia.
Another composite material of interest is beryllia, particle-reinforced beryllium.
The compound bonds to alumina, porcelain, beryllia, ceramics, glass, plastics, laminates, and metals.
In addition glass, ceramic, beryllia, zirconia, and quartz are available, as well.
The helices are supported by three beryllia support rods on which "vanes" are deposited by conventional low-cost thin-film sputtering and etching techniques, thereby precision shaping the required dispersions of the circuits at will.
the world's leading producer of beryllium, its alloys and beryllia ceramic, reported a net loss in the third quarter of 1991, following two quarters when sales had been significantly less than in the previous year.
The most remarkable property exhibited by AlN is its high thermal conductivity - in ceramic materials second only to beryllia.
