Composition of Oxides - Patent and Technology Report - Key Players, Innovators and Industry Analysis
Dolcera, Nov 2011, Pages: 47
The different oxides such as SiO2, Li2O, Al2O3, CeO2, CaO, P2O5, V2O5, K2O and ZrO2 are present in glasses at different compositions. These oxides are responsible for making the glass brittle and transparent. The short story is that glass is a super-cooled liquid, meaning that it is rigid and static but does not change molecularly between melting and solidification into a desired shape. Glass is one the most versatile substances on earth, used in many applications and in a wide variety of forms, from plain clears glass to tempered and tinted varieties, and so forth. Glass occurs naturally when rocks high in silicates melt at high temperatures and cool before they can form a crystalline structure. Obsidian or volcanic glass is a well known example of naturally occurring glass, although it can also be formed by a lightning strike on a beach, which contains silicate-rich sand. Early forms of glass were probably rife with impurities and subject to cracking and other instability, but examples of glass beads, jars, and eating materials first appeared in ancient Egyptian culture.
The Lithium silicate ceramic glass was used for manufacturing of blocks and subsequent fabrication of single dental crowns with the aid of the CAD/CAM process. The presence of germanium dioxide makes the glass more cast-able with higher density and higher flexural strength than the lithium disilicate free of germanium dioxide. In some US patent preparation of shaped translucent lithium disilicate glass ceramic products from a mixture of basic components (SiO2, Al2O3, K2O, Li2O, plus pigments and fluorescent oxides) was mentioned. Germanium dioxide increases the final density of the glass resulting in higher values of flexural strength than the lithium disilicate glasses free of germanium dioxide (Castillo et al, 2009).
This report focuses on finding the key innovators and the industry ecosystem through relevant patents, clinical trials and university data encompassing the presence of SiO2, Al2O3, Li2O, CeO2, CaO, P2O5, V2O5, K2O and ZrO2. Dolcera has a standardized and tested procedure to formulate comprehensive patent search strategies to retrieve all the relevant patents. The report highlights year-wise patent activity (trend line) along with the key industrial players in the field. The different companies have been categorized based on their position in the value chain. A comprehensible result in the form of the Dolcera dashboard has been given. The dashboard links the companies in each category to their patents, hence making an interactive platform for analysis. Companies have also been segregated based on their geographical distribution. Dolcera has retrieved close to 400 relevant patents related to Nano-emulsions in foods, covering around 17 countries. Furthermore, patents have been mapped to commercially available products produced by the respective assignees and other licensees. The report also highlights different universities and research institutes active in the research of the said technology area, hence pointing out industry opportunities.
