METHOD OF FABRICATION OF QUARTZ CONTAINERS Russian patent published in 2009 - IPC C23C16/00 C30B13/14 C30B15/10 

FIELD: metallurgy.

SUBSTANCE: organic silanes with atomic ratio of silicon and carbon 1.0:(1.0÷4.0) are used as source carbon containing compound. Coatings are made by successive multiple alternative moistening of surface of the container with organic silanes, by drying them under normal conditions, by forming polymer film and by annealing. The first annealing of settled polymer film is performed in oxidising atmosphere at 450-650°C within 20-30 min, while the second and successive annealing of settled polymer films onto formed oxide coating is carried out in inert atmosphere at 700-800°C during 30-60 minutes.

EFFECT: invention improves quality of protective coating on quartz surface of containers due to their upgraded density and strength preventing interaction of melted material with working walls of container of any shape, it also reduces impurity of produced material with diffusing additives of chemical elements from quartz.
