摘要:
The invention relates to a process for atomizing a dispersible liquid material or a mixture of dispersible liquid materials, characterized in that the dispersible liquid material (3) or the mixture is dispersed in the form of particles (7) by spraying at least one stream of solid particles (6) which are reactive as a result of their partial or total coating onto the material and the particles (7) are collected in a receiving medium.
摘要:
Arsine or phosphine are thermally decomposed to form a molecular beam of arsenic or phosphorous by using the inside surfaces of a thermal decomposition duct (11) made of quartz or of boron nitride and heated on the outside by radiation from a filament (30). Pierced internal partitions (6a, 6b, 6c, 6d) having successive circumferentially offset holes (6p, 6q, 6r, 6s) increase the decomposition surface area and prevent a molecule from passing through the duct along a straight line.
