ELASTIC CONSTANTS OF SINGLE CRYSTALS

H. P. R. Frederikse

This table gives selected values of elastic constants for single crystals. The values believed most reliable were selected from the original literature. The substances are arranged by crystal system and, within each system, alphabetically by name. A reference to the original literature is given for each value; a useful compilation of published values from many sources may be found in Ref. 1. Different crystal types are covered in the tables as follows, which have different numbers of independent elastic constants C_ij depending on crystal symmetry.

Table No.	Crystal Type	Elastic Constants included
1	Cubic	C₁₁, C₁₂, C₄₄
2	Tetragonal	C₁₁, C₁₂, C₁₃, C₁₆, C₃₃, C₄₄, C₆₆
3	Orthorhombic	C₁₁, C₁₂, C₁₃, C₂₂, C₂₃, C₃₃, C₄₄, C₅₅, C₆₆
4a	Monoclinic	C₁₁, C₁₂, C₁₃, C₁₅, C₂₂, C₂₃
4b	Monoclinic	C₂₅, C₃₃, C₃₅, C₄₄, C₄₆, C₅₅, C₆₆
5	Hexagonal	C₁₁, C₁₂, C₁₃, C₃₃, C₅₅
6	Trigonal	C₁₁, C₁₂, C₁₃, C₁₄, C₃₃, C₄₄

Column definitions for the tables are as follows.

Column heading	Definition
Name	Name of the single crystal; names are ordered alphabetically within crystal type
Mol. form.	Molecular formula of the single crystal
ρ	Density
T	Temperature at which the elastic constant is measured, in K
C_nm, etc.	Elastic constants, in units of 10¹¹ N m^-2, for the single crystal; refer to table above for range of n and m included for each crystal type
Ref.	Reference

Data given for the single-crystal elastic constants C_i_j, in units of 10¹¹ N/m², which is equivalent to 10¹² dyn/cm².

Searching for Chemicals and Properties

The CRC Handbook of Chemistry and Physics (HBCP) contains over 700 tables in over 450 documents which may be divided into several pages, all categorised into 17 major subject areas. The search on this page works by searching the content of each page individually, much like any web search. This provides a challenge if you want to search for multiple terms and those terms exist on different pages, or if you use a synonym/abbreviation that does not exist in the document.

We use metadata to avoid some of these issues by including certain keywords invisibly behind each table. Whilst this approach works well in many situations, like any web search it relies in the terms you have entered existing in the document with the same spelling, abbreviation etc.

Since chemical compounds and their properties are immutable, a single centralised database has been created from all chemical compounds throughout HBCP. This database contains every chemical compound and over 20 of the most common physical properties collated from each of the >700 tables. What's more, the properties can be searched numerically, including range searching, and you can even search by drawing a chemical structure. A complete list of every document table in which the compound occurs is listed, and are hyperlinked to the relevant document table.

The 'Search Chemicals' page can be found by clicking the flask icon in the navigation bar at the top of this page. For more detailed information on how to use the chemical search, including adding properties, saving searches, exporting search results and more, click the help icon in to top right of this page, next to the welcome login message.

Below is an example of a chemical entry, showing its structure, physical properties and document tables in which it appears.

Accessibility

Accessibility in Handbook of Chemistry and Physics 103rd Edition

The Voluntary Product Accessibility Template (VPAT) is a self-assessment document which discloses how accessible Information and Communication Technology products are in accordance with global standards.

The VPAT disclosure templates do not guarantee product accessibility but provide transparency around the product(s) and enables direction when accessing accessibility requirements.

Taylor & Francis has chosen to complete the International version of VPAT which encompasses Section 508 (US), EN 301 549 (EU) and WCAG2.1 (Web Content Accessibility Guidelines) for its products.
