ABSTRACT:
A reactor for use in chemical or physical vapor transport film or crystal growth experiments includes a composite reaction tube which is comprised of an open stainless steel tube which is fused to a closed glass tube. The stainless steel portion of the reaction tube supplies mechanical strength and rigidity for sealing purposes while the glass portion of the composite tube permits visual observation of crystal growth within the composite tube.
