FABRICATION OF FLUID DEVICES AND FLUID DEVICES PRODUCED - A simplified explanation of the abstract

This abstract first appeared for US patent application 18283239 titled 'FABRICATION OF FLUID DEVICES AND FLUID DEVICES PRODUCED

Simplified Explanation

The abstract describes a patent application for a process and device for forming a monolithic ceramic fluidic device with a tortuous fluid passage.

• The device is a ceramic fluidic device with a tortuous fluid passage.
• The ceramic body has a continuous and uniform distribution of grains.
• The process involves using a positive fluid passage mold within binder-coated ceramic powder.
• The mold is removed after heating the pressed body, and then the body is sintered.
• The relationship between stability characteristics of the powder and mold prevents discontinuities in the final product.

Potential Applications

The technology could be used in various industries such as medical devices, chemical processing, and fluidic systems for analytical instruments.

Problems Solved

The technology solves the problem of creating ceramic fluidic devices with complex fluid passages and smooth interior surfaces without discontinuities.

Benefits

The benefits of this technology include improved fluidic performance, durability, and resistance to corrosion compared to traditional fluidic devices.

Potential Commercial Applications

The technology could be commercialized for use in medical devices, laboratory equipment, chemical processing plants, and other industries requiring precise fluid control systems.

Possible Prior Art

One possible prior art could be the use of traditional molding and sintering techniques for ceramic components with fluid passages. However, the specific process and device described in this patent application may offer unique advantages in terms of stability and uniformity.

What materials are used in the ceramic powder?

The abstract does not specify the exact materials used in the ceramic powder. Further details on the composition of the ceramic powder could provide insights into the properties of the final ceramic fluidic device.

How does the relationship between stability characteristics of the powder and mold prevent discontinuities?

The abstract mentions a relationship between stability characteristics of the powder and mold to prevent discontinuities in the final product. Exploring this relationship in more detail could shed light on the mechanisms behind ensuring the integrity of the ceramic fluidic device during the manufacturing process.

Original Abstract Submitted

A device and a process for forming a monolithic substantially closed-porosity ceramic fluidic device having a tortuous fluid passage extending through the device, the tortuous fluid passage having a smooth interior surface, a material of the ceramic body having a continuous and uniform distribution of grains at least between opposed major surfaces of the ceramic body. The process includes positioning a positive fluid passage mold within a volume of binder-coated ceramic powder, pressing the volume of ceramic powder with the mold inside to form a pressed body, heating the pressed body to remove the mold, and sintering the pressed body. A relationship between a first stability characteristic of the volume of ceramic powder and a second stability characteristic of the mold prevents discontinuities in the pressed body after pressing and/or during heating.
