Manufacturing method for silane type product

The invention provides a manufacturing method for a silane type product. The manufacturing method for the silane type product comprises the following steps: A, preparing magnesium silicide from silica powder and magnesium powder in the presence of a catalyst; B, enabling the magnesium silicide and ammonia chloride to react to generate silane type gas and hexammoniated magnesium chloride in the presence of liquid ammonia and the catalyst; C, performing a separation reaction on the hexammoniated magnesium chloride to obtain magnesium chloride and liquid ammonia; D, performing electrolysis on the magnesium chloride to obtain magnesium powder and chlorine gas; E, performing a reaction on the chlorine gas obtained in the step D and the liquid ammonia obtained in the step C to generate ammonia chloride, and applying the obtained ammonia chloride to the step B. The manufacturing method for the silane type product is completely completed under a chloride-free and halogen-free environment; the risk of chloride and halogen in the subsequent use can be fully eliminated; furthermore, all side-products and intermediate products can be recovered and reutilized, so that the top requirement of environment protection is achieved.
