Abstract

Melting the material in the powder phase (Ie the material in the installment of the glass) was processed in two steps. The first step is using touch. Increased gas / solids to heat the material up to Medium temperature The second step melts the material quickly in the secondary space with the material in the period and a near nitrogen-free heat source may be used. At first to bite the fine powder
