This precision drilled quartz plate, sized 290x6x40mm, features accurately drilled holes with tight dimensional tolerance. Manufactured from high purity quartz, it delivers 1100°C heat resistance and superior HF/strong acid chemical durability—ideal for tube furnace gas distribution baffles, vacuum coating workpiece fixtures, semiconductor sintering carriers and chemical laboratory partition plates.

Product Parameters

Key Features

• Precision Drilled Holes – Accurately drilled holes with tight dimensional tolerance for consistent gas flow distribution and reliable mechanical performance in high-temperature environments.
• 1100°C Heat Resistance – Maintains structural integrity and dimensional stability under sustained high temperatures without deformation—no chipping or cracking under thermal cycling.
• HF & Strong Chemical Resistance – Superior to borosilicate glass, withstands hydrofluoric acid and concentrated acids/alkalis for demanding chemical processing and cleaning applications.
• High Purity, No Contamination – 99.99% pure quartz with zero metal impurity precipitation, preventing contamination in semiconductor and high-purity material processing.
• High Transmittance – Clear optical transmission for visual monitoring of processes through the plate during operation.

Applications

1. Tube Furnace Equipment

Internal ventilated baffle supporting material samples while allowing uniform shielding gas circulation, remaining dimensionally stable at sustained high temperatures without generating debris.

2. Vacuum Coating Industry

Process tooling fixture for vacuum coating machines, positioning and securing workpieces while allowing process gas circulation through precision holes under high-temperature chamber and corrosive gas source conditions.

3. Semiconductor & New Materials

Raw material sintering carrier plate with through-holes for gas venting and impurity exhaust, with high purity construction that does not contaminate sintered products.

4. Chemical Laboratory Testing

Gas-liquid reaction separator and acid pickling filter plate, resistant to HF and concentrated acid/alkali corrosion for demanding chemical processing applications.

Advantages over Borosilicate Glass

Compared to borosilicate glass drilled plates, this quartz plate offers full HF corrosion resistance, sustained 1100°C operation, excellent thermal shock resistance without edge chipping or cracking, higher drilling precision, and high purity suitable for clean production environments—making it the preferred choice for high-temperature, corrosive and contamination-sensitive applications.
