Product Description

Product Description

Milky white quartz ring

Milky white quartz ring, also named opaque fused silica plate, is made of high-purity fused silica with uniform micro air bubbles distributed inside. It presents a milky white opaque appearance, different from transparent quartz glass. The tiny bubbles scatter light evenly, bringing excellent light diffusion, heat insulation and light shielding performance. All products can be customized into round, square, rectangular, flanged and special shapes with cutting, drilling, polishing and edge finishing processing as per customer drawings.

Superior Properties

Excellent Light Diffusion & Light Blocking 
Micro bubbles uniformly disperse light to eliminate hot spots, achieve soft and even illumination; low visible light transmittance, ideal for shading and uniform lighting fixtures.
Ultra High Temperature Resistance 
Max long-term service temperature up to 1100–1200℃, softening point at 1730℃, won't deform under continuous high heat environment.
Outstanding Thermal Shock Resistance 
Low thermal expansion coefficient (5.4×10-⁷ /℃), withstand rapid heating & cooling without cracking or breakage.
Superior Heat Insulation Performance 
Low thermal conductivity, effectively block heat radiation, widely used as high-temperature thermal insulation gaskets and baffles.
Strong Chemical Inertness & Corrosion Resistance 
Resistant to most acids, alkalis and organic solvents, insoluble in water, stable in harsh chemical working conditions.
High Mechanical Hardness & Durability 
Mohs hardness 7, high compressive strength, wear-resistant and long service life.
High Purity Quartz Raw Material 
SiO2 content ≥99.9%, low impurity content, no contamination for semiconductor, laboratory and precision heating equipment.
