The Synthesis And Processing Of Ceramics And Ceramic...

INTRODUCTION | 1 Polymer derived ceramics (PDC) were first introduced over thirty years ago, and are a fundamental material in high demand today. Over the years, these materials have been heavily studied to better understand how to manufacture them and determine their desired properties. Such materials include coatings, ceramic fivers, and ceramics containing properties that allow them to have high stability at high temperatures. Desired properties of PDC typically include high resistance to decomposition, phase separation, crystallization, high chemical durability, semi-conductivity, and creep. [4] This paper will discuss the synthesis and processing of ceramics and ceramic composites using soft materials such as pre-ceramic polymers. The potential for materials for a large variety of applications in harsh environments, pertaining mainly to the mechanical properties of PDCs, will also be discussed. PROCESSING TECHNOLOGIES | 2 There are three basic steps in order to process PDC. These include synthesis of preceramic from a specific monomer, crosslinking of polymers at low temperatures which allow for networks to form, and finally ceramization by pyrolysis. Some of the most common monomers which can be used consist of polysilanes, polycarbosilanes, polysiloxanes, polysilazanes, and polysilylcarbodiimides. There are several procedures in order to attain these figure 18.1 indicates some of the methods of creating some preceramics through various methods outlined [1].

If you believe this, we’re going to tell you that you are largely wrong. At least within the realm of business innovation, virtually everyone has some capacity for creativity and innovative thinking. Even you. So using the example of Jobs, let’s explore this ability to think different. How did Jobs come up with some of his innovative ideas in the past? And what does his journey tell us?
