Graphite Boat/ Tray For Powder Metallurgy and Hard Alloy
As one of the most commonly used processes for coating, PECVD graphite boats are widely used in the production process of semiconductors and solar cells. As the carrier of silicon wafer, graphite boat is one of the most ideal materials. It plays a vital role in the uniformity and color difference of the surface coating. It requires high purity, corrosion resistance, excellent bending strength and good The electrical conductivity. Graphite boat commonly used in photovoltaic industry, reliable quality, comfortable price. Various specifications can also be tailored for customers.
A grooved graphite boat, which includes a plurality of W-shaped bidirectional chute with two opposite groove surfaces and bottom supporting protrusions, a bottom surface, an upper end surface, an inner surface, an outer surface, and a stop opposite to the upper end At least one exhaust through groove is respectively designed on the two groove surfaces, and an edge protection groove is respectively designed at the intersection of the bottom support protrusion and the two opposite groove surfaces. The bottom surface is designed with a through groove parallel to the W-shaped two-way chute and whose cross-sectional shape is approximately Λ-shaped at the lower part of the protrusion formed by any two adjacent W-shaped bidirectional chute. The utility model enables the hard alloy long thin sheet products to be uniformly degummed during the hydrogen degumming and vacuum sintering processes, avoiding product warpage and deformation, and having a large product loading capacity and few consumables.
