Ceramic Fiber Vial

A ceramic fiber vial is a small container, typically cylindrical, constructed from ceramic fiber materials. These vials are designed for high-temperature applications and specialized storage needs.

Material

The primary material is ceramic fiber, commonly alumina silicate fiber, though other compositions like zirconia or magnesia fibers may be used depending on the specific application requirements. These fibers are bound together to form a porous, lightweight structure. The composition dictates properties like maximum operating temperature, thermal shock resistance, and chemical compatibility.

Purpose

Ceramic fiber vials are used primarily for:

• High-Temperature Storage: Containing materials at elevated temperatures without significant heat loss.
• Sample Containment: Holding samples during high-temperature reactions, calcination, or other thermal processes.
• Protection from Contamination: Providing a barrier to prevent sample contamination, particularly in reactive atmospheres.
• Gas Collection: Some designs are used to collect gases evolved during heating processes.

Function

The key functions stem from the material properties:

• Thermal Insulation: Ceramic fiber is an excellent thermal insulator, minimizing heat transfer and maintaining a stable internal temperature.
• High-Temperature Resistance: Capable of withstanding temperatures up to 1600°C (2912°F) or higher, depending on the fiber composition.
• Chemical Inertness: Generally resistant to attack by most chemicals, although specific compatibility depends on the fiber type and the chemical involved.
• Low Thermal Expansion: Reduces the risk of cracking or breakage during heating and cooling cycles.
• Porous Structure: Allows for gas permeability in certain applications.

Usage Scenarios

• Laboratory Research: Used in materials science, chemistry, and physics for high-temperature experiments.
• Calcination: Holding samples during calcination processes in furnaces.
• Catalyst Testing: Containing and protecting catalysts during high-temperature testing.
• Thermal Analysis: Used in techniques like thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).
• Metallurgical Applications: Holding metal powders or compounds during sintering or other heat treatments.
• Gas Source: Acting as a source of gases generated through thermal decomposition.

Common Types

• Alumina Fiber Vials: Most common type, offering good general-purpose performance.
• Zirconia Fiber Vials: Higher temperature resistance and better chemical stability than alumina.
• Magnesia Fiber Vials: Used in applications requiring resistance to molten metals or slags.
• Closed-End Vials: Sealed at one end to contain gases or prevent sample loss.
• Open-End Vials: Open at both ends for gas exchange or sample observation.
• With/Without Caps: Some vials are supplied with caps made of materials like alumina or quartz to further contain samples or control the atmosphere.
• Various Sizes: Available in a range of diameters and lengths to suit different sample volumes and furnace configurations.

The declared goods are ceramic fiber vials, which are containers typically used in laboratory or industrial settings for storing or transporting small amounts of substances. They are characterized by their composition of ceramic fibers, providing high-temperature resistance and chemical stability.
