Molecularly Designed Innovations

Cerablak™ technology is enabling new possibilities in high temperature materials science.  Its original discovery stemmed from an accidental experimental result that yielded a nanocomposite consisting of carbon encapsulated in aluminophosphate glass that is stable above 1400°C in air. The black glass-ceramic led to the name “Cerablak™.”  By further refining this discovery via molecular design, several unique products have been developed including transparent ultra-thin films. Cerablak™ is establishing a global footprint across diverse markets and applications with unmatched high temperature performance.

utf characteristics 5Cerablak® UTF is a dense, hermetic-quality barrier film that provides long-lasting protection for substrates in extreme heat and other harsh environments. Due to the ultra-thin nature of the film, its stability under thermal shock or thermal cycling conditions is excellent despite relatively large thermal mismatch with substrates. Cerablak® UTF can be deposited using dip, spray, flow, and spin processes, and does not require any special surface preparation or pretreatments. Due to the phosphate nature of the material, the adhesion is excellent.

 

This patented inorganic glassy film is chemically inert and stable at temperatures up to 1400°C and in hazardous environments including oxidizing, reducing, or ultra-high vacuum (UHV) conditions. In addition to surface protection in extreme conditions, Cerablak® UTF also provides unique benefits as an electrically insulating and planarizing layer, well-suited for advancing next generation flexible electronics.


This solution-based, wet deposition process is economical, scalable, and ready to meet the demands of today’s manufacturing requirements.

Cerablak® HTP is a high-emissivity spray-on coating that provides thermal insulation and environmental protection. Utilizing a conventional off-the-shelf spray gun and a proprietary slurry feedstock solution, Cerablak® HTP is deposited as an inorganic coating with a brief thermal treatment after deposition. The black version of Cerablak® HTP is particularly unique in blocking radiant heat.  Thermal conduction by radiation becomes critical above 700°C and Cerablak® HTP can provide durable thermal protection in oxidizing, reducing, and even vacuum environments such as in semiconductor manufacturing or space exploration.

cmc characteristics


Cerablak® CMCs represent a new advancement in the field of ceramic matrix composites and hold great promise in addressing 21st century challenges in thermal management. These composites are bulk materials made from commercially available fiber reinforcements (Nextel™-grade fibers from 3M™) and our proprietary matrix material. Ceramic composites are an emerging class of materials that combine the thermal and oxidative stability of ceramics with the toughness and damage tolerance of metals. Cerablak® is an excellent matrix material for composites due to its simple and low-cost solution processing, as well as unparalleled thermal stability and compatibility with most ceramic fiber materials.

Cerablak® SHS are unique, robust, low-energy layers with environmental stability superior to typical commercial organic coatings. Today’s hydrophobic coatings typically rely on the functionality of a monolayer of organic material, and environments where the coatings are subjected to high temperatures and/or mechanical abrasion can cause irreparable damage. As a result, the functional groups that cause hydrophobicity in those materials can be permanently damaged.
 
Unlike those materials, the Cerablak® SHS chemistry exhibits the ability to heal with time, resulting in a regenerative, protective, water-repelling effect (hydrophobicity). The ability to regenerate the low-energy surface after exposure to extreme environments such as high temperatures or highly abrasive conditions results in only a temporary degradation of the surface properties. The resulting durability of Cerablak® SHS can therefore far exceed that of conventional coatings. For water-shedding and easy-to-clean properties under harsh environmental conditions, Cerablak® SHS can provide enhanced stability and protection compared to typical organic solutions.

htscharacteristics

Cerablak® HTS represents a revolutionary advancement in the sealing of materials with fine open porosity. Gaseous or vapor ingress into fine pores have plagued the performance of materials such as refractories for many decades and the problem is growing as temperatures are being increased in industrial applications. With Cerablak® HTS comes an elegant solution, resolving sealing issues in a wide range of porous materials, including refractories, advanced ceramics and composites, and thick ceramic coatings. Most importantly, the sealant does not detrimentally impact designed thermal or mechanical properties. The process of applying the sealant is simple and utilizes a shelf-stable clear chemical formulation. A vacuum infiltration scheme is used to infiltrate fine porosity and deposit a hermetic-quality barrier film on the pore walls which helps limit diffusion of environmental species into the bulk, thus preventing corrosion. In some cases, the material can be essentially sealed against gas diffusion as proven by helium leak testing.
