Powder Metallurgy

Powder metallurgy is the process of using ceramic powder (composite powder) as raw material, under certain temperature and pressure conditions, to produce various shapes of components and finished products through processes such as pressing and sintering.

In powder metallurgy of ceramics, the commonly used cellulose ether type is Hydroxypropyl Methylcellulose (HPMC), Our Celopro® series product can be fully mixed with ceramic powder to evenly distribute various components, ensuring the uniformity of the performance of the green body in the subsequent forming process, and also helping ceramic powder to better bond and form during the forming process. HPMC is mainly used in the field of honeycomb ceramics in metallurgy.

Recommended Solutions

Hydroxypropyl Methylcellulose(HPMC)

HPMC participates in two steps in the powder metallurgy process of ceramics:

The first stage is the mixing stage: adding HPMC during the mixing process of ceramic powder. It can be fully mixed with ceramic powder to evenly distribute various components, ensuring the uniformity of the performance of the green body during the subsequent forming process.

The second stage is the molding stage: helping ceramic powders to better bond and form during the molding process. Whether it is compression molding or other molding methods, the addition of cellulose ether can improve the plasticity and flowability of ceramic powder, making it easier for the powder to fill the mold and form a regular shaped and structurally dense body.

HPMC has good thickening performance, which can adjust the viscosity of ceramic powder slurry, improve its flowability and plasticity. It can better fill the mold with ceramic powder during the molding process, especially suitable for molding complex shapes.

HPMC is mainly used in the field of honeycomb ceramics in metallurgy. After adding HPMC, the operability of the honeycomb ceramic product film tire is improved, and the honeycomb ceramic product has better body strength. It also plays a lubricating role in the extrusion process of thin-walled honeycomb ceramics, making the surface of honeycomb ceramics smooth and delicate, ensuring the toughness of low thickness pore walls. In addition, HPMC also provides functions such as moisture control, enhanced bonding, and reduced shrinkage, thereby improving the processing performance and product quality of the extrusion process.

Product Features and Advantages

Excellent adhesion

HPMC has good bonding properties, which can firmly bond ceramic powder particles together, improve the strength and integrity of the body, and reduce damage and cracking during handling, drying, and other processes.

Good water retention

Helps to maintain moisture in ceramic slurry, prevent rapid evaporation of moisture, and ensure the stability and operability of the slurry during the molding process. This is particularly important for processes that require longer molding time or molding in a dry environment.

Strong adaptability

It can maintain good performance stability under different temperature, humidity and other conditions, and is suitable for various ceramic powder metallurgy production environments.

Good environmental friendliness

Cellulose ether is a derivative of natural polymer materials, non-toxic, harmless, biodegradable, and meets environmental requirements.

Excellent lubricity

HPMC can reduce the friction between ceramic powder particles and between powder and mold, making the molding process smoother, reducing mold wear, and improving production efficiency.

Frequently Asked Questions

What is the general dosage of cellulose ether added in ceramic powder metallurgy?

The dosage of cellulose ether added in ceramic powder metallurgy is usually 0.1% -5% of the mass of ceramic powder. This range is relatively broad, and the specific amount of addition may vary due to various factor,such as differences in particle size and shape, different molding processes, and varying performance requirements for the final ceramic product,etc.

What are the applications of cellulose ether in powder metallurgy of ceramics?

In powder metallurgy of ceramics, non-ionic cellulose ether are commonly used. This type of cellulose ether is mainly used in the ceramic industry for the production of new honeycomb ceramics and environmentally friendly ceramic products.

What additives need to be added in addition to cellulose ether during the powder metallurgy process of ceramics？

Lubricants, fluxing agents, adhesives, dispersants，etc.
