contrast the crystal structures and crystal chemistry of quartz‚ α-FePO4 and β-FePO4. Both α-FePO4 (space group: P3121) and α-quartz (space group: P3121 and P3221) belong to the trigonal crystal system‚ while β- FePO4 (space group: P6422) and β-quartz (space group: P6222 and P6422) belong to the hexagonal crystal system. At relatively low temperature‚ FePO4 is tetrahedral in structure. This is similar to the tetrahedral structure of quartz. As temperature increases‚ the tetrahedral structure gradually

Case Study II: Aqualisa Quartz Introduction and Problem Statement Aqualisa‚ a premium British shower manufacturer‚ is experiencing teething problems with its new line of electronic mixed shower products – Quartz. Despite being hailed as “a breakthrough in shower technology” (Case p. 6)‚ early sales were dismal. Plumbers‚ the main channel of Aqualisa’s products‚ have developed an ‘electronic phobia’ since the late 1980s when early electronic showers failed‚ hurting Quartz by association. Furthermore

Situation Aqualisa Quartz‚ a significantly innovative product developed by Aqualisa‚ in terms of both cost and quality‚ has been facing challenges in the market since its launch four months ago. The product described by one of the customers (a plumber) is a ’push-fit-connect-you’re done’ shower and offers the customers ’what they (the plumbers) want’. Despite the above facts‚ Quartz has experienced poor sales and has not met the company’s expectations. Brand awareness was low in the industry

Paragraph 1 FePO4 is distinct from other α-quartz isotypes because its A cation is a transition metal. It is studied at different temperature ranged from 294K to 1073K by neutron powder diffraction. At relatively low temperature‚ it adopts the structure of α-quartz‚ which is tetrahedral and shown below. At high pressures‚ a phase change occurs to a more dense octahedral structure‚ which is known as β-phase. The transition temperature is 980K. During the first-order transition‚ discontinuities

Paragraph 1: Crystal chemical relationship between quartz (SiO2) and FePO4 The following describes the crystal chemical relationship between quartz (SiO2) and FePO4. At temperatures below 980 K‚ FePO4 exists as alpha- FePO4. Beyond the temperature mark of 980 K (at 980 K or higher)‚ FePO4 exists as beta- FePO4. The geometrical symmetry of single cell of α- FePO4 is trigonal while the geometrical symmetry of β- FePO4 is octahedral structure. At the alpha phase‚ the cell parameters shoots up by a

Executive Summary: Rawlinson is considering whether to change marketing strategy for the Quartz in order to sell 100 or 200 a day to break through the mainstream. To generate sales momentum‚ most important‚ Rawlinson should come up with tactics to encourage product trial by plumbers; secondly‚ demonstrate product benefit to consumer‚ and build premium image and sales channel with luxury property developer. Situation Analysis: Company: Rawlinson believed Aqualisa’s profit advantage is vulnerable

“Aqualisa Quartz: Simply a Better Shower‚” HBS 9-502-030; Rev July 10‚ 2006 Problem ID: Aqualisa hopes to grow the brand through the introduction of a new line‚ the Quartz shower. Initial launch results have been disappointing‚ and the managing director of Aqualisa would like to breathe new life into the launch through a new marketing strategy. The intended result is higher sales‚ wider brand recognition and a larger share of pocket through add-ons and other computerized features to the Quartz system

Paragraph 1: Quartz‚ also known as SiO2‚ has a tetrahedral structure that is similar to FePO4 under normal circumstances. However‚ there is the presence of a few differences. For FePO4‚ it’s a cation is a transition metal‚ unlike silicon which is a metalloid. This study summarises the changes in structure of FePO4 over a range of temperatures. Quartz belong to the trigonal crystal system‚ but not considered to be part of the rhombohedral lattice system. Both α- quartz and β-quartz are chiral crystal
