[Development] Achieving thick film yttria with ceramic DIP coating.

Improvement of plasma resistance in semiconductor manufacturing processes, setters for molten metals, crucibles, rollers, etc., enhanced wettability for longer lifespan, and coating on graphite is also possible!

Various setters for firing such as MLCC and ferrite components, plasma-resistant materials for semiconductor manufacturing equipment, crucibles for various metal melting, transport rollers, and various quartz components. We have developed a dip coating technique for ceramics that was generally considered difficult, enabling thick film coatings on various fine ceramics, quartz, isotropic graphite, and refractory materials that are hydrophobic. Features: 1. Unique dipping technology provides: - High freedom of shape, strong adhesion to substrates, uniform film thickness, and high surface roughness. - While the design freedom for the coated object increases, consultation is required based on the shape. 2. Wide range of coating materials and target substrates: - Coatable ceramic materials: Most oxides and non-oxides (BN, SiC, Si3N4, etc.) - Target substrates: General fine ceramics, isotropic graphite, glass such as quartz, refractories, and metals (heat resistance temperature confirmation required). 3. High advantages of dipping over other coating methods: - Low cost (mass production effect) - Capable of handling three-dimensional structures, hollow shapes, and large sizes (size confirmation required). Film Thickness: Standard target film thickness: 50μ±5–10μ We optimize the use of composite ceramic films according to applications. Please feel free to contact us.
